The Extech SDL350 Hot Wire Thermo-Anemometer Datalogger displays and stores air velocity and temperature readings. Temperature readings from the thermometer built into the probe or from an externally connected type K or J thermocouple temperature probe can be displayed and recorded. Data is stored on an SD card for transfer to a PC.
