Fluke 922 Airflow Meter

Analyze airflow. Easily. The 922 Micromanometer. Today’ s HVAC technicians want a simple solution for diagnosing ventilation issues. Differential pressure measurements only tell part of the story. Technicians also want to measure air velocity and flow, without having to resort to expensive, difficult to use, specialist tools. The Fluke 922 makes airflow measurements easy by combining three tools: differential pressure, airflow, and velocity into a single, rugged meter. Use the Fluke 922 micromanometer to: Measure pressure drops across key HVAC equipment to drive peak performance and extend equipment life Match ventilation to occupant loads Monitor indoor vs. outdoor pressure relationships and manage the building envelope Promote indoor comfort and quality Perform duct traversals for accurate airflow readings Technical Specifications Air Pressure Range/ Resolution/ Accuracy ± 4000 Pascals / 1 Pascal / ± 1 % + 1 Pascal ± 16 in H2O / 0.001 in H2O / ± 1 % + 0.01 in H2O ± 400 mm H2O / 0.1 mm H2O / ± 1 % + 0.1 mm H2O ± 40 mbar / 0.01 mbar / ± 1 % + 0.01 mbar ± 0.6 PSI / 0.0001 PSI / ± 1 % + 0.0001 PSI Air Velocity Range/ Resolution/ Accuracy 250 to 16, 000 fpm / 1 fpm / ± 2.5 % of reading at 2000 fpm ( 10.00 m/ s) 1 to 80 m/ s / 0.001 m/ s / ± 2.5 % of reading at 2000 fpm ( 10.00 m/ s) Air Flow ( Volume) Range/ Resolution/ Accuracy 0 to 99, 999 cfm / 1 cfm / Accuracy is a function of velocity and duct size 0 to 99, 999 / 1 m3/ hr / Accuracy is a function of velocity and duct size 0 to 99, 999 l/ s / 1 l/ s / Accuracy is a function of velocity and duct size Temperature Range/ Resolution/ Accuracy 0 ° C to 50 ° C / ± 1 % + 2 ° C / 0.1 ° C 32 ° F to 122 ° F / ± 1 % + 4 ° F / 0.1 ° F General Specifications Operating Temperature 0 ° C to + 50 ° C ( + 32 ° F to + 122 ° F) Storage Temperature -40 ° C to + 60 ° C ( -40 ° F to + 140 ° F) Relative Humidity 0% to 90% , non-condensing IP Rating IP40 Operating Altitude 2000 m Storage Altitude 12000 m EMI, RFI, EMC Meets requirements for EN61326-1 Vibration MIL-PREF-28800F, Class 3 Max Pressure at Each Port 10 PSI Data storage capacity 99 readings Warranty 2 years Power, battery life Four AA batteries Battery Life 280 hours without backlight, 60 hours with backlight
