Units of Measure: inWC, inHg, psi, mmWC, mmHg, Pa, kPa, mBar, fpm, cfm, l/s,
m/s, F, C, RH%, lb/ft3
Range & Accuracy
Airflow Velocity: 44 – 12,320 fpm ± 0.5%
Temperature: -40 to 185°F ± 0.5°F
Humidity: 0-95% ± 3%
Pressure: 300-1100 mbar ± 0.12 mbar
*Please note that we are often asked the maximum volume of airflow, this is totally
dependent on the size of the duct. For example: 12,320 fpm through a 20” x 24” grille is
41,028 CFM. So the range of this meter goes high enough to satisfy any practical HVAC
application.
