Manual

The Fluke 975 AirMeter test tool raises indoor air monitoring to the next level by combining five powerful tools in one, rugged and easy-to-use handheld device. Use the Fluke 975 to optimize HVAC ventilation settings for ASHRAE 62 recommendations, actively monitor conditions that promote a productive environment, and quickly and accurately address occupant comfort complaints the first time. The Fluke 975 AirMeter measures temperature, velocity, humidity, CO2, and CO.

Responding to comfort-related calls from occupants and determining whether adequate vantilation exists is simple with the Fluke 975. Use the AirMeter to test for dangerous carbon monoxide leaks and perform duct traversals. With the Fluke 975, users can efficiently verify and optimize the operation of building HVAC control systems to manage energy costs.
