Air Quality Monitor Gas Analyzers Portable Carbon Dioxide Meter Indoor Detectors Outdoor Monitoring Equipment Room Co2 Detector Environment conditions Working environment: -10.0℃ to 50.0℃/14.0℉ to 122.0℉；1-85%rh (no condensation) Storage environment：-20 to 60℃/-4℉ to 140℉;1-90%rh (no condensation） 1.General Description Co2 is colorless and tasteless at normal temperature and pressure. It is slightly soluble in water and reacts with water to produce carbonic acid. Co2 only accounts for 0.03% of the fresh air Co2 is harmful to human body, if breathe high concentration co2, people May be at risk of carbon dioxide intoxication. Symptoms of carbon dioxide toxicity include headache, irregular heartbeat, nausea,unconsciousness, or even death. This co2 monitor measures co2 concentration, temperature and humidity. It is widely used in homes, shopping malls, offices,cinema, classroom and other public places. 2.Features ◆ Big size color va display ◆ 3 colors LED alarm and buzzer alarm ◆ Enable/disable buzzer alarm ◆ Co2, ambient temperature, humidity,clock ◆ Measure and display co2 concentration, temperature and humidity at the same time ◆ Calendar / time display ◆ Re-chargeable lithium battery ◆ Type-c charging interface ◆Desktop and wall mounted ◆ Battery level indication 3.Accessories (1) type-c cable (2) user’s manual CO2 Range Accuracy Resolution 400～6000ppm ±(50ppm+5%of reading) 400~5000PPM 1 Temperature -10~50℃ -14℉~ 122℉ ±1.5℃/2.7℉ 0.1 Humidity 1%RH~99%RH 30%~90%RH:±5.0%RH Others:±10%RH 1 CO2 sensor type Non dispersive infrared (NDIR) gas sensor Data update ＜1S Power supply 3.7V 18650-2000mA TYPE-C Charging interface（DC5V 1A adapter） Working Environment -10~50℃ /14.0℉~122.0℉；1-85%RH (No condensation) Storage Environment -20 to 60℃/-4℉ to 140℉； 1-90%RH (No condensation) Size 91.8×97.8×36mm Weight 198g
