  • 20 point average for Air Flow
  • Super large (9999 count) LCD Backlit Display
  • 3% velocity accuracy via low friction 2.83"D (72mm) ball bearing vane wheel on 3.9ft (120cm) cable
  • Complete with vane sensor with 3.9ft (120cm) cable, 9V battery, and protective rubber holster

Essential Info

This instrument measures Air Velocity, Air Flow (volume), Air Temperature (with probe) and Surface Temperature (with the InfraRed function). The large, easy-to-read backlit LCD includes primary and secondary displays plus numerous status indicators. The InfraRed feature includes a laser pointer for convenient targeting.
In addition, the meter can store 16 area setting dimension for easy recall. Proper use of this meter will provide years of reliable service.

This tool does an excellent nice job in calculating the CFM based on the measured duct opening. It reads the airspeed then uses the duct dimensions to display CFM. As a bonus it does IR temperature readings as well. Easy to use with a big bright display that is backlit at the touch of a button. It includes a very nice case that also holds the instruction book.
