Multifunctional Carbon Dioxide Tester Our 3 In 1 CO2 monitor can accurately detect the current CO2 concentration，temperature，and humidity around you in real time，makes it easy to understand your indoor air condition. CO2 measurement range: 370-9999PPM（accuracy：±3%of readings of ±40PPM）. Temperature measurement range:-4-140℉（ -20-60℃）（±3℃）. Humidity measurement range: 0-99%RH（±5%）
About CO2 & What to use CO2 monitor for Excessive CO2 will cause many problems,such as discomfort,odor “stuffiness” And possible health symptoms, headaches,dizziness,nausea and others.This CO2 detector made for avoid these situations,also set three thresholds for your reference,Hazard Alert (can be customized).LCD display green smile for normal (370-699ppm),yellow neutral for warning stage(700-1399ppm),red angry for dangerous stage(1399-9999ppm).
CONVENIENT CALIBRATION:To ensure the accuracy of measurement, this CO2 monitor supports the calibration function.Press the 【SET】key for 5 seconds,put the CO2 monitor in an open environment stand for 10 minutes to calibrate this CO2 meter.when the screen shows Countdown Time ：599 ,When the countdown is over, means calibration is over.Recommended calibration prior to use.
Carbon dioxide detector can be widely used in agricultural planting, breeding, and industry, such as planting greenhouses to detect the amount of gas fertilizer applied, the ventilation status of livestock farms,beer.Not only that, in our daily life environment such as: kindergartens, schools, office buildings, shopping malls, supermarkets,stations, hospitals and other public places.
Please note that the temperature display of our CO2 detectors shows both Celsius and Fahrenheit readings in real time. If you are familiar with Fahrenheit, you can just read the Fahrenheit value.
