The Fluke 975 AirMeter With Velocity is a test tool that delivers productive readings of temperature, velocity, humidity, CO2 and CO through an easy to use display. This unit is optimized for any HVAC technician under ASHRAE 62 recommendations. The 975 simultaneously measures, records and displays the readings through its backlit LCD display. Get one-touch airflow and velocity readings through the probe on the unit. Measure the wet bulb and dew point temperature as well as the outside air calculation percentage. The unit’s self-test function at startup makes sure that you are getting the best readings throughout the job. The unit comes with an air velocity probe, FlukeView Forms software and a USB interface for downloading data to your PC. The 975 has a temperature range of -5 to 122 degrees Fahrenheit and a display resolution of .1 degrees Fahrenheit.
