Description

The 77597 AZ Portable CO2 CO Temperature Humidity Meter is a multi detector, which could measure the indoor air quality index, including the CO2, CO concentration, dew point, wet bulb value and air temperature.

The 77597 AZ Combo CO CO2 device could be used as the CO2 data logger for the air quality index in all work space, office, hospital, school, station or home. It is and ideal instrument for indoor air quality (IAQ) diagnosis.

The portable AZ 77597 Combo CO2, CO, Temperature RH Meter uses NDIR (non-dispersive infrared) technology to ensure the reliability and long term stability. It’s useful in verifying HVAC system performance and air ventilation control.
