The TM-4002 hot wire anemometer is used to undertake measurements of air velocity and air temperature / humidity in spaces where the vane anemometer cannot be used, typically in HVAC ducts.and vents. This instrument benefits from a LCD triple display, which can show both air speed and temperature, and the backlight makes this display easy to read in dimly lit areas.
The TM-4002 is able to calculate both air velocity, and air volume and has a wide array of features designed to make testing simple and fast.
The TM-4002 hot wire anemometer lends itself to many applications, including air balancing, fire matrix testing, paint booths, ventilation systems, and environmental testing. The probe is housed within a telescopic device for access to hard to reach areas.
- The Tenmars TM-4002 displays air (wind) speed in meters/second, feet/minute, kilometers/hr, knots, and miles/hr
- Displays maximum and minimum readings and holds any reading
- Manual Data Memory and read function (99 records)
- Dew point, Wet Bulb calculation
