CDM 901 is a micro-controller based instrument which shows real time CO2 values along with Temperature and Humidity. The monitor is based on improved technology, which does not require a pump. An in-built cataloguer can be used to record the values and a software is provided to download the data to MS Excel for trend analysis.Measuring Principle: Non-Dispersive Infra-red (NDIR), Ranges Available: 0 - 2000 ppm, 0 - 1%, 0 - 5%, The CDM 901 CO2 monitor is based on sensor technology which consumes very low power.
