One Tool. Get More Done.

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 measures:

  • Temperature
  • Velocity
  • Humidity
  • CO2
  • CO

Use the Fluke 975 AirMeter test tool to:

  • Respond to comfort-related calls from occupants.
  • Verify the operation of building HVAC control systems.
  • Determine whether adequate ventilation exists.
  • Monitor air flow and velocity.
  • Test for dangerous carbon monoxide leaks.
  • Perform duct traversals.
  • Optimize HVAC systems to manage energy costs
