840034 Sper Vane Anemometer and Psychrometer

840034 Sper Vane anemometer and psychrometer measures air speed, temperature and humidity. Calculates air volume, BTU, wet bulb and dew point.

The 840034 Sper Vane Anemometer and Psychrometer  is an excellent tool to use in the field for HVAC, IAQ and environmental measurements. It is small, handheld with replaceable vane probe assembly attached via coiled cable. With auto-ranging air speed measurement the instrument relieves the operator of having to change ranges during measurements. Directly reads air speed in m/s and ft/s, temperature in °F and °C, and humidity. When duct dimensions are input, the 840034 calculates air volume in CFM (ft³/min) and m³/sec. Dew point is calculated in °F and °C, as is wet bulb temperature. BTU is calculated in kw over the range 0 ~ 99999 kw.

Features min/max/average, hold, auto power off, LCD backlight and computer interface, which allows for convenient data collection and analysis.
