The Fluke 975V AirMeter with Velocity Probe 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 975V 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 975V was designed to support engineers across the globe, featuring a multi-language user interface (English, French, German, Portuguese, and Spanish) and US and Metric measurement options. Automatic backlighting and power-off allow for hassle-free operation. Users have the option of logging in single-point or continuous data modes and can download stored data with the bundled USB cable and FlukeView Forms software. The AirMeter is built for portability and can be powered by rechargable lithium battery, ac power, or backup power supply of three AA batteries.

The Fluke 975V measures, calculates, and displays:

Temperature, dew point, and wet bulb all measured in Celsius (°C) or Fahrenheit (°F).
Relative humidity (%RH).
Carbon monoxide (CO) levels measured in ppm.
Carbon dioxide (CO2) levels measured in ppm.
Air velocity (standard and actual) measured in mps or fpm.
% outside air based on temperature or CO2.
Flow rate displayed in m3 /s or cfm.
Absolute barometric pressure- shown at startup only.
Minimum, maximum, and average readings for temperature, relative humidity, wet bulb, dew point, velocity, CO, and CO2.
