CDM-15 CO2 Monitor

Extremely convenient and unique meter for the constant monitoring of the CO2 content in indoor spaces.  The humidity and indoor temperature are also indicated.

Unique quality of this meter is in addition to the high accuracy also the high reaction speed. The CO2 content is indicated in real-time.  Many CO meters indicate a short reaction time, but because the sensors are built-in, the reaction time is often more than an hour, making them hardly useful for use in schools.
