Extech AN340 CMM CFM Anemometer/Psychrometer Data Logger

The Extech AN340 CMM CFM Anemometer/Psychrometer Data Logger is capable of measuring wind speed from 0.5m/s to 20m/s; air temperature from -20˚C to 60˚C; and humidity from 0.1% to 99.9% RH. It can also calculate wet bulb and dew point values as well as cubic metres per minute as a volume flow reading.

Measurements are taken via the Extech AN340’s 18mm diameter rotating vane probe that is attached to the anemometer via a 1m cable. There are various measurement functions such as min/max/average and data hold and it has internal storage for up to 99 readings.

In datalogging mode, the Extech AN340 can connect to a PC over a USB connection and saves up to 12000 readings with time and date stamps. The sampling rate is adjustable between 1s and 5-hour intervals.

The Extech AN340 comes supplied with an external mini vane probe, Windows compatible software, USB cable, six AAA batteries and hard carry case. It is supplied with a one-year warranty.
