This thermo-anemometer measures not only the air speed but the air temperature as well. This makes this meter ideal for HVAC applications where hot air blowers are present. Check the air speed coming out of hot air vents as well as air conditioning units or fans. This meter can be put in place and left to data log readings with an adjustable sampling rate from 1 second all the way up to an hour.

The information is recorded onto a removable SD card for easy and fast data transfer to a PC. This meter also measures the air temperature, making it ideal for heat vents and heating system testing. The telescoping probe is also great for testing wind speeds up to 45 mph (31 knots).
