Air Quality Monitor

Recent research shows that poor air quality in classrooms particularly high CO2 concentrations affects learning abilities 

The ET102 is a hand held portable air quality tester that simultaneously monitors, displays and gives audible alarm for 5 air quality criteria : the concentration of CO2, Total volatile Organic Compounds (TVOC), Formaldehyde (HCHO), Temperature, and Humidity in the environment. 3 Emojis also indicate the air quality levels as Excellent, Good and Pollution

Used inside or outside buildings to measure the toxicity of air particularly in confined spaces such as classrooms, meeting rooms, dwellings  and vehicles.

The meter has an inbuilt Lithium battery and a USB charger so can be used as a portable device or remain plugged in all day to continuously monition changing conditions or build up of CO2 etc. if windows left closed all day

• Switchable between Centigrade and Fahrenheit with audible alarm setting on/off switch.

• Built-in 1800mAh capacity lithium battery, with USB charging cable.
