Congratulations on your purchase of the Extech SDL300 Thermo-Anemometer Datalogger. This
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 an 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
