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), which had been widely used for indoor air quality measurement.
AZ7755 CO2 & Temperature & Relative Humidity Meter was being designed and manufactured by AZ Instrument, a well experienced manufacturer for Environmental Measuring Instrument.
