Top 8 Best Carbon Dioxide

Know The Air Around You The air quality tester has built-in advanced Infrared NDIR laser scattering detection sensors designed to accurately track air quality including CO2, PM2.5PM1.0 and PM10 particulate matter, temperature and humidity. Tips Please let the device work short mins outdoor before use for most accurate results.. 10 hours long standby Auto Alarm Function The built-in 2000 mAh battery can provide more than 10 hours of standby time when fully charged, in addition to real-time power through the included usb charging cable, this enables long-term monitoring of air quality level. Press the main function key twice quickly to turn onoff the automatic alarm function An alarm will be issued when the CO2 reading exceeds 1000ppm.. 2.8inch Instant Readout Professional sensors require a sampling time of only 1.5s, which can display the current air quality on the screen in real time. The CO2 detector uses a 2.8in large size display, which can show the readings simply and intuitively The reading of PM1PM2.5PM10 automatically switches every 5s.. Portable CO2 Detector A portable detector the size of a palm, is easy to carry and can detect the gas quality in bedroom, living room, kitchen, office, car, school, hotel, campground and other environments. the data can indirectly understand the presence of second-hand smoke and mold, which will send out an alarm for your health.. Easy Operation Customer Service Just one button operation to switch onoff, with a detailed instruction manual, in addition, if you have any questions about our products and services, please feel free to contact us any time, we are always committed to providing you with quality products and services.

MONITORING ANALYSIS Allows continuous monitoring of CO2, RH Temperature Level. Data output to PC every 2 seconds.. MULTIPLE MEASUREMENT DISPLAYS AT ONCE- CO2, Temperature, and Relative Humidity readings are all shown on the LCD display at the same time. NORMAL MAX MIN AVERAGE 15mins 8hrs MODE- It can show not only the normal, maximum and minimum CO2 readings but also the weighted average CO2 readings in the past 15mins STEL mode and 8 hours TWA mode.. AUDIBLE CO2 SOUND- The alarm beeps when the CO2 Level exceeds the preset value. The alarm threshold is adjustable.. NDIR SENSOR for CO2 DETECTION- Non-dispersive infrared technology is used to ensure the reliability and long-term stability. Measures 09999ppm while 02000ppm can maintain a high accuracy at - 50ppm.

Built-in Relay Function Controls the ventilation system to automatically maintain the CO2 level that you set or specify.

Ideal indoor air quality meter for home, laboratories, hotels, etc. Sound Warning Alarm notifies operator when CO2 levels reach or exceed a preset threshold. Power Supplied by Battery Included or 9V Adaptor . Optional Software CD for PC Connection Online Logging is also possible.. Measuring RangeCO2 09999ppm,20019999 out of scale, Resolution 1ppm,0.1CF, 0.1RH.

This controller has a built-in photo sensor that overrides the CO2 control and shuts off the CO2 device when it senses darkness.It helps you to Monitor Controlling CO2 value in Greenhouse or residential. With minimum and maximum CO2 levels. In Plant Mode, when the minimum level is sensed, power is supplied to a CO2 generator or regulator via the output socket. When the maximum level is reached, the power is turned off. Opposite in Human Mode.. Has Built-in photo sensor that overrides the CO2 control and shuts off the CO2 device when it senses darkness.. Display CO2 chart with adjustable time scale weekdayhourminauto ,Sensing probe cable is 4.5 meter long to extend your measure spot 4.5 meter away from display. Accurate 2-Channel low drift NDIR CO2 measurement , Programmable CO2 control value zone value allows you to set desired CO2 level for different plants..

Handheld digital meter measures ambient level of carbon dioxide CO2 to monitor indoor air quality and performance of heating, ventilation, and air-conditioning systems. Displays current CO2 levels, long-term average CO2 levels measured over an 8-hour period, and short-term average CO2 levels measured over a 15-minute period. Alarm notifies operator when CO2 levels reach or exceed a preset threshold, CO2 measurement up to 9999 ppm. Liquid crystal display LCD shows ambient CO2 levels, as well as air, wet bulb, or dew point temperature and humidity. Manual calibration helps ensure accurate humidity and CO2 readings.
