Measure Air Velocity and Temperature Simultaneously

Extech Instruments SDL300 Metal Vane Thermo-Anemometer DataloggerThe Extech SDL300 Thermo-Anemometer Datalogger meter displays and stores air velocity and temperature readings. Temperature readings from the thermometer built into the vane probe or from an externally connected type K or J thermocouple temperature probe can be displayed and recorded. Data is stored on the included 2GB SD card for transfer to a PC. In addition, an RS232 port allows data streaming to a PC. This meter is shipped fully tested and calibrated, with proper use, will provide years of reliable service.
