Psychrometer / Anemometer

This unique instrument combines the features of an anemometer and a psychrometer. Measures air speed, air volume, BTU (British Thermal Units), air temperature, dew point, wet bulb and humidity. Excellent for HVAC, IAQ and environmental work. Auto ranging with air velocity in m/s or ft/s, air volume in CFM or m3/sec and temperature in °C or °F. Features min/max/avg, hold, auto power off, LCD backlight and a computer interface. The probe detaches for easy replacement and repair. In order to connect this model to a computer to stream data, you will need the USB Cable 840054 and Data Acquisition Software 840052. Comes in a hard carrying case complete with a probe, tripod mounting screw and 4 AAA batteries. Uses optional AC Adapter (840027).
