TM-4002 Hot-Wire Air Velocity Meter

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.
