Otherwise, it willbe calibrated as 400ppm by default and leads toinaccurate measurements.UNPACKING AND INSPECTIONYour shipping carton should include:1 CO2-200 CO2 Meter1 Adaptor1 User manual1 Plain white boxIf any of the items are damaged or missing, returnthe complete package to the place of purchase for an exchange.2INTRODUCTIONThank you for purchasing this CO2 meter. It measures CO2 level, air temp., dew point, wet bulb temp. and humidity and is an ideal instrument for indoor air quality (IAQ) diagnosis.Poor indoor air quality is considered unhealthy because it causes tiredness, loss of ability to concentrate, and even illness (ex. Sick Building Syndrome). IAQ monitoring and survey, especially on CO2 level and air ventilation become widely applied in public areas such as offices, classrooms, factories, hospitals and hotels. It is also suggested in regulations of industrial hygiene in some countries. (Appendix)With NDIR (non-dispersive infrared) sensor used, thisCO2 meter is stable in long term monitoring. And the built-in relay for alarm output is especially useful in ventilation control and HVAC system performance verification.Features• Triple displays of CO2 level, temp. and humidity.• Stable NDIR sensor for CO2 detection.• Statistics of weighted averages (TWA & STEL)• Visible and audile CO2 warning alarm• Alarm output for ventilation control• Battery and adaptor power supply• ABC(Automatic Baseline Calibration) and manualCO2 calibration• USB PC connection3OPERATION1. Plug in the adaptor and the meter turns onautomatically with a short beep. It performs30 seconds countdown (Fig.1) for meter warmup, then enters normal mode with current CO2,temperature, and humidity readings displayed.2. The meter starts taking measurements whenpower on and updates readings every second. Inthe condition of operating environment change(ex. from high to low temp.), it takes 30 sec torespond for CO2 sensor and 30 minutes for RH.3. Press “p/DP/WB” to switch temperaturesdisplay. The lower left display will cycle from airtemperature, dew point temp., and wet bulbtemp. (Fig. 2)4. Press “MNX/AVG/q” to see the minimum,maximum, and weighted average readings.Each press of it displays MIN, MAX, STEL, TWA insequence and returns to normal mode. In MIN andMAX modes, it shows the minimum and maximumreadings of CO2 on main display, and of AIR/DP/WBT temperatures and humidity on the lowerdisplays. In STEL and TWA modes, the main displayshows the weighted average of CO2 readings forthe past 15 minutes (STEL) and 8 hours(TWA), butthe lower displays are the current AIR, DP/WBtemperatures and humidity readings.NOTE:• If the meter is turned on for shorter than 15minutes, the STEL value will be the weightedaverage of readings taken since power on. Samefor TWA values appear before 8 hours.• It takes at least 5 minutes to calculate STEL andTWA. The display shows “----” during the first 5minutes from power on (Fig. 3).4Alarm OutputThe meter features visible and audible alarm to give warnings when CO2 concentration exceeds the limit. Users can set up 2 limits: An upper limit for alarm threshold that requires air conditioning and a lower limit to stop the alarm. (See P1.0 in setup for setting alarm limits).It emits beeps(Abt.80dB) with blinking LED when CO2 level goes over the upper limit. Beeps can be stoppedby pressing any key or automatically stops whenCO2 reading falls below lower limit. If the beeper is temporarily shut, it will sound again when readingsfall below lower limit and then go over the upper limit again, or users press “RESET” for more than 1 secondto activate it. LED alarm keeps blinking when beeps are manually shut. It stops only when readings fall under the lower limit.The meter is designed with a relay to send outputfor further connection. When CO2 readings go overthe upper limit and cause alarming. The relay picks up automatically and sends output. It can be connected to a ventilation system or activator for conditioning the air quality. The relay will drop out when CO2 readings fall under the lower limit.SetupThe advanced setup mode lets you customize your meter.3 types parameters are available.P1.0: CO2 AlarmP3.0: Temperature unitP4.0: ABC selectionP1.0 CO2 alarm: upper & lower limitsHold down “SET” under normal mode for more than 1 sec to enter set up mode. To exit setup, press “CAL/ESC” in P1.0, P3.0, or P4.0.5When entering setup mode, P1.0 and “AL” are displayed on the LCD (Fig. 4). Press “SET” again to go into P1.1 for setting CO2 upper limit. The current set value will be blinking on LCD (Fig.5). Press “p/DP/WB” to increase the value or “MNX/AVG/q”to decrease. Each press tunes 100 ppm and the alarm range is from 100 to 9900ppm. When the preferred value is set, press “SET” to go into P1.2 for lower limit setting. After both settings are done, press “SET” to save or “CAL/ESC” without saving and return to P1.0.P3.0: Temperature scalePress “p/DP/WB“ in P1.0 to access P3.0 for setting up temperature scale. Press “SET” and it goes into P3.1 with blinking °C or °F current set on the lower left display.To switch °C or °F, press “p/DP/WB “or “MNX/AVG/q”. Then press “SET” to save the setting or “CAL/ESC” without saving and return to P3.0.P4.0: ABC selectionPress “p/DP/WB“ in P3.0 or “MNX/AVG/q” in P1.0 to access P4.0 for selecting ABC function. Press “SET” and it goes into P4.1 with blinking “dis” default (Fig. 6) on the lower left display. To enable the ABC function, press “p/ DP/WB“ or “MNX/AVG/q” and “En” blinks for choice. After the preferred selection is done, press “SET” to save the setting or “CAL/ESC” without saving and return toP4.0.Calibration ModeCO2 calibrationABC (Automatic Baseline Calibration)ABC is to implement baseline calibration toeliminate the zero drift of the NDIR sensor. Itcalibrates the meter at the minimum CO2 readingdetected during 7 days continuous monitoring(power on). It’s not suitable to implement ABC inclose area with higher CO2 level all the time. TheABC default is off. To enable the function, pleaserefer to SETUP P4.0.6Manual calibrationThe manual calibration is suggested to be done inoutdoor area with ventilating fresh air where CO2level is around 400 ppm. Do not calibrate in placescrowded with people or close to where with highCO2 concentration such as ventilating outlets orfireplaces.1. Place the meter in the calibration site. Turn on themeter and hold down “CAL/ESC” and “p/DP/WB“simultaneously to enter CO2 calibration mode.400ppm and “CAL” are blinking on the LCD whileperforming calibration. (Fig. 7)2. Wait about 5 minutes until it stops blinking andthe calibration completes and back to normalmode.3. To abort the calibration, turn “RESET” over asecond.Humidity calibration1. Plug the sensor probe into 33% salt bottle. Holddown “CAL/ESC” and “MNX/AVG/q” undernormal mode to enter 33% calibration. “CAL” andcalibrating value (32.7% if at 25°C) are blinkingon the LCD with current temperature at the left.Meter is now calibrating, and will finish in about60 minutes when “CAL” and humidity value stopblinking.2. After 33% calibration, plug the sensor probe into75% salt bottle, then press “SET” to enter 75%calibration. “CAL” and calibrating value (75.2%if at 25°C) are blinking on the LCD with currenttemperature at the left. Meter is now calibrating.Wait about 60 minutes until blinking stops, thencalibration is completed and it returns to normalmode.73. Users can also calibrate either point. To calibrate33% only, press “CAL/ESC” to exit when 33%calibration is completed. To calibrate 75% only,press “p/DP/WB“ or “MNX/AVG/q” within 5minutes while initializing 33% calibration. And itskips 33% and enters 75% calibration.USB Interface CapabilitiesThe USB cable and software (optional kit) are required to transfer data to a PC.

由主机和外设附件两部分组成:主机包括二 氧化碳模块、血氧模块、监护模块;外设附件包 括鼻氧管(或三通管)、采样管、脱水器和脉搏 血氧探头。
• 通气功能有改变时,PETCO2接近PACO2和PaCO2,故 PETCO2逐渐增高是反映通气不足,是非常迅速、敏感的 指标,而特异性一般。当PETCO2与PaCO2存在差值时, 其敏感性和特异性下降,由于通气不足的临床表现不敏感, 也无特异性,故PETCO2波形的辅助诊断价值较高。其多 数由于VT设置偏小。也可能是回路漏气等原因。
• (4)、监测呼吸机的故障; • (5)、评估心肺复苏的有效性:在心肺复苏中自主循环恢复
者ETCO2迅速升高,明显高于未恢复时; • (6)、转运过程中监护。
• 3、呼吸内科、老年干部科: • (1)、监测通气功能,ETCO2和PaCO2有很好的相关性,
能反应PaCO2大概的数值和变化; • (2)、评估支气管扩张剂药效; • (3)、评估排痰后呼吸道通畅情况; • (4)、评估无创呼吸机治疗效果; • (5)、监测呼吸机的故障;
四、名词解释:
1、ETCO2( PETCO2 ):呼气末二氧化碳分压值; PaCO2 :动脉血中的二氧化碳分压值;反应呼吸性酸碱 性失衡的重要指标 PACO2 :肺泡气体中的二氧化碳分压值。PETCO2≈ PaCO2 ≈PACO2

二氧化碳检测器是一款用于检测二氧化碳浓度的仪器,具有高精度、长寿命、体积小,易维护等特点,广泛应用于各个领域如发酵过程控制,农业暖房、温室CO2浓度监测。
多种输出方式可选。
二氧化碳变送器具有多种量程可选、适应恶劣环境、安装简便和现场维护容易等特点,可供用户选择,二氧化碳变送器被广泛应用于写字楼、公共场所、温室大棚、厂房、酒店宴会厅、实验室、净化间、培养箱、安全报警、泄漏监测以及需要良好通风的恶劣环境等。
为此,二氧化碳变送器在自动化中有着广阔的应用前景。
所谓变送器是把物理测量信号或者普通电信号转换成标准电信号输出,或能够以通讯协议方式输出的设备,二氧化碳变送器最大的贡献是在工农业生产中的应用,工农业生产中经常需要测量各种非电物理量(例如温度、压力、速度和空气等) ,它们都需要转换成模拟量电信号才能传输到几百米外的控制室或显示设备上。
第一章用户需求分析设计的目的、意义和背景利用传统方法对温室环境进行监控,采用人工方法检测和控制,及其浪费人力资源,而且精度低,常常不能达到理想效果。
目前国内推行科学种植技术,对温室大棚采用人工的方法控制温度和湿度,还通过CO2增施肥技术给大棚补充二氧化碳,虽然有科学资料可以借鉴,但是利用人工方法存在着很多弊端。
尤其是对CO2浓度的监控,对于温度和湿度的监控,还可以通过温度计和湿度计的读数进行人工操作,而对CO2浓度的监控就没有那么简单。
目前我国大多数大棚所采用的CO2增施肥方法非常笨拙,只是靠人工在固定时间对大棚进行CO2施肥,对CO2施肥的多少无法掌控,而植物对CO2的需求并不是越多越好,有资料表明:CO浓度维持在100ppm 植物正常进行光合作用,浓度在600-2019ppm光合作用为最佳状态,显然对CO2浓度的控制要得当。
近年来,随着单片机功能的日益强大和计算机的广泛应用,人们对大棚内参数检测的准确性和控制的稳定性越来越高。
本设计就是针对此问题,设计相对准确的、稳定的CO2浓度监控装置,由于系统的灵活性和模块化,可以广泛应用于温室大棚环境监控。
随着传感器和计算机技术的不断进步和完善, CO2检测仪器开始发展起来。
根据国内目前红外二氧化碳气体传感器技术,制作了一种具有广泛开的应用前景, 并以其测量范围宽、响应时间快、抗干扰能力强、成本低等特点的CO2气体检测仪。
第二章市场分布目前检测二氧化碳的方法主要有化学法、电化学法、气相色谱法、容量滴定法等,这些方法普遍存在着价格贵,普适性差等问题,且测量精度还较低。
而传感器法具有安全可靠、快速直读、可连续监测等优点。
目前各种检测用的二氧化碳传感器主要有固体电解质式、钛酸钡复合氧化物电容式、电导变化型厚膜式等,这些传感器存在对气体的选择性差、易出现误报、需要频繁校准、使用寿命较短等不足。
而红外吸收型二氧化碳传感器具有测量范围宽、灵敏度高、响应时间快、选择性好、抗干扰能力强等特点。
为此本设计采用红外吸收型二氧化碳传感器,整个电路设计力求简单易用,快速直读,价格低廉。
2.1 市场上常用的二氧化碳的常用方法2.11 气相色谱法气相色谱法是将二氧化碳在色谱柱中与空气的其他成分完全分离后,进入热导检测器的工作臂,使该臂电阻值的变化与参考臂电阻值的变化不相等,惠斯通电桥失去平衡而产生的信号输出。
在线性范围内,信号大小与进入检测器的二氧化碳浓度成正比。
从而进行定性与定量测定。
在进样3mL 时,测定浓度范围是0.02%~0.6%,最低检出浓度为0.014%。
由于采用了气象色谱分离技术,所以空气、水、CO等均不影响测定,但是色谱分析条件常因实验条件不同而有差异,所以应根据所用气相色谱仪的型号和性能,制定能分析二氧化碳的最佳色谱分析条件。
且在测量过程中需要配制标准气,并用纯氮气对标准气进行稀释,过程繁琐,且操作时间较长,难以保证测量准确度。
2.12 滴定法滴定法是用过量的氢氧化钡溶液与空气中二氧化碳作用生成碳酸钡沉淀,采样后剩余的氢氧化钡用标准乙二酸溶液滴定至酚酞试剂红色刚褪。
由容量法滴定结果除以所采集的空气样品体积,即可测得空气中二氧化碳的浓度。
滴定溶液需要前两天配置好,所需时间较长,不能被广泛采用2.13 电容式CO2传感器电容式传感器是把被测量的变化转换成电容量的变化的传感器,主要是因为金属氧化物的介电常数一般比其他碳酸盐要大,利用电容的变化来检测CO2气体浓度。
常采用溶胶一凝胶法,以醋酸钡和钛酸丁酯为原料,乙醇和醋酸为溶剂制备了BaTi03纳米晶材料。
采用这种纳米晶材料为基体,制备电容式CO2气体传感器,其缺点是检测低浓度CO2时输出信号小,且容易受到其他气体的影响2.14 红外吸收型CO2传感器红外吸收型CO2传感器是利用红外线作为介质的测量系统,它利用二氧化碳吸收波长4.26um红外线的物理特性来有选择地准确测量二氧化碳的分压,其吸收关系从Lamber.Beer定律。
红外吸收型气体分析检测仪一般由红外辐射源 4 测量气室,波长选择装置(滤光片),红外探测装置等组成。
如果气体的吸收光谱在入射光谱范围内,那么红外辐射透过被测气体后,在相应波长处会发生能量的衰减,未被吸收的辐射被探头测出,通过测量该谱线能量的衰减量来得知被测气体浓度。
红外线气体检测仪的优点是测量范围宽、选择性好、防爆性好、设计简便、价格低廉。
因此,红外吸收型二氧化碳传感器具有测量范围宽、灵敏度高、响应时间快、选择性好、抗干扰能力强等特点。
为此本设计采用红外吸收型二氧化碳传感器,整个电路设计力求简单易用,快速直读,价格低廉第三章适用范围及用途二氧化碳及温度检测仪可以在农业、养殖业、工业领域中广泛使用,如:种植大棚、畜牧养殖场,啤酒、碳酸饮料、节能环保产品的生产过程及井下作业安全生产等。
在我们日常生活环境中如:幼儿园、学校,、写字楼、商场、超市、车站、医院等公共场所,对二氧化碳浓度的监测可以改善空气的的质量,从而提高学习、工作效率;预防传染病流行,确保公共健康安全。
3.1 蔬菜大棚的应用3.11 种植大棚使用二氧化碳检测仪二氧化碳是绿色植物进行光合作用的原料之一,作物干重的95%来自光合作用。
因此,二氧化碳也就成为影响作物产量的重要因素。
塑料大棚栽培使作物长期处于相对密闭的场所中,棚内二氧化碳浓度一天内变化很大,日出前达到最大值1000~1200ppm,日出后2.5~3小时降为100ppm 左右,仅为大气浓度(330ppm)的30%左右,而且一直维持到午后2小时才开始回升,到下午4时左右恢复到大气水平。
蔬菜需二氧化碳浓度一般1000~1500ppm。
因此,塑料大棚内二氧化碳亏缺相当严重,成为影响塑料大棚蔬菜产量的重要因素。
在塑料大棚中安装二氧化碳监测仪可以保证在二氧化碳监测仪浓度不足的情况下及时报警,从而使用气肥。
保证蔬菜、食用菌、鲜花、中药等提早上市、高质高产。
3.12 施用二氧化碳对蔬菜产量的影响据中国农业信息网报道:黄瓜、西红柿、西葫芦是常见的三种蔬菜,针对这一实际情况,分别在这三种蔬菜上进行了二氧化碳施肥实验,增产效果非常显著。
三种蔬菜上分别施用二氧化碳浓度1000毫克/千克,黄瓜平均每667平方米增产465.5千克,增产27.1%;西红柿平均每667平方米增产410.7千克,增产23.6%;西葫芦平均每667平方米增产373.2千克,增产21.9%。
3.13 施用二氧化碳对蔬菜植株性状的影响塑料大棚蔬菜施用二氧化碳后,植株性状明显好于未施的。
黄瓜施用二氧化碳后,植株生长良好,施的比不施的植株增高15~20厘米,多长2~3片叶,叶片显著大而厚,单株叶面积大0.19~0.3平方米,提早2个节位结瓜,且坐果率高,单株结瓜多3~5个,施的瓜条呈黑绿色,不施的瓜条顶端4~5厘米呈黄色。
而且,施用二氧化碳气肥还能增强植株的抗寒、抗病能力。
西红柿施用二氧化碳后,植株明显增高,叶片浓绿变厚,果实提早成熟,且果实表面发亮。
西葫芦施用二氧化碳比不施的植株长相变化特别明显,施的叶片肥大,茎粗,植株大而壮,不施的植株小而弱。
而且施的表现结果早。
3.2 适用的范围3.21 大型畜牧养殖场碳浓度超标的时候,监测仪报警并启动风机自动更换新鲜空气;同时随时监测圈舍的温度及通风率。
3.22 做节能环保产品厂家这里就以做节能门窗的厂家为例:现在有好多做节能门窗的不用开窗户就可以通风,厂家为了证明产品的节能性与通风性,他们在安装完节能门窗后就送给客户一个二氧化碳及温度监测仪,以便客户自己随时测量室内二氧化碳浓度,这款机器还能同时监测室内的温度与通风率,有了这些随时可以科学监测的数据,这些客户感觉使用节能门窗后也就会更放心。
3.23 井下安全生产:井下作业时会产生很多有毒气体和二氧化碳,其中二氧化碳浓度过高导致人在井下严重缺氧,导致无法呼吸不能正常工作,在井下的工作环境放置二氧化碳监测仪就能随时监测二氧化碳的浓度是否在可以正常工作的范围内,同时可以监测井下的温度,这样就避免一些意外的发生及做好相关的防护工作。
3.24 幼儿园、办公室、学校、超市:例如:学校教室上课时会有几十个学生或上百个学生,时间久了不开窗二氧化碳浓度就会升高,会导致师生们头昏或有困意,降低学习效率。
若每个教室里放有二氧化碳监测仪,把机器调到一个合适的报警值,如果报警了就可以开窗换一下新鲜的空气,即能保证空气的质量,也能让同学们有个安静的不受外界干扰的学习环境。
在人员较密集的公共场所,如超市、车站等,空调长时间的运转也导致了资源的浪费。
放置二氧化碳及温度监测仪可以随时监测这些公共场所的二氧化碳浓度及室内温度,根据需要调节通风率及温度,这样就会节省大量的资源与开支。
