Anemometer (Air Velocity+ Air Flow+ Air Temp)

3 Measurements in one instrument.
Air flow: CMM( M3/min) and CFM(FT3/min)
Air velocity: m/s, ft/min, km/h, knots, mile/h.
Air temperature: Degree C and F.
3 air flow mode: Instant, 2/3rd Velocity Max, Average
Use Low friction ball vane wheels to make sure high accuracy in high and low velocities.
Recall function for maximum and minimum record
Data hold function
High accuracy and special function built-in microcomputer circuit design.
Auto power off , Low battery indication.

Use fast-response-time Thermistor sensor for temperature measurement.
Separate probe for different environment measurement.
