The user can easily enter the size of the duct opening and the HHF142 automatically calculates the volume flow rate from the duct. The duct size is automatically stored in memory on turn-off and up to 10 unique duct sizes can be stored and recalled for frequent use.

Rated 5 out of 5 by from HFF142 is a great little tester Purchased to measure airflow of HEPA filters in a clean-room. Works perfectly and as intended. I would like it to have had a longer cable for a extended reach, but am very pleased with the ease and accuracy of this unit.

Rated 5 out of 5 by from The HHF142 Delivers I have used hot-wire anemometers and swinging-vane anemometers, but this rotating-vane anemometer is by far the best. Quite pleased, and very easy to use.

Thank you for your inquiry and apologize that the anemmeter is an causing issue. Replacing the probe would be the first option and in the event, it continues to behave, please have it returned for evaluation.
