Fluke 975 AirMeter

Discontinued

The Fluke 975 AirMeter is a five-in-one IAQ and HVAC solution that measures temperature, relative humidity, CO₂, CO, and air velocity with the optional probe. It provides dew point, wet-bulb, and percent outside air calculations, along with Min/Max/Average logging and automatic barometric pressure compensation. The unit records up to 25,000 data points, supports USB download with FlukeView Forms, and includes visual and audible alarms for CO and CO₂ monitoring.

ATEC offers the 975 base unit and the 975V with the velocity probe available for rent.
