CO2 meter, also been called as CO2 detector or Carbon Dioxide detector, it’s the device that can detect the presence of Carbon Dioxide (CO2).
CO meter, also been called as CO detector or Carbon Monoxide detector, it’s the device that can detect the presence of Carbon Monoxide (CO).
Both of them had been widely used for indoor air quality measurement.
AZ77597 Combo CO2 & CO & Temperature & Relative Humidity Meter was being designed and manufactured by AZ Instrument, a well experienced manufacturer for Environmental Measuring Instrument.
