The bright white display and ruggedized holster and wrist strap let you take the Fluke 922 into less than ideal environments. The color-coded hoses help you keep track of where your readings are coming from. The simple, intuitive interface means you can measure pressure, velocity, or airflow at the push of a button. The Fluke 922 helps you analyze airflow. Easily. Powerful meter provides differential and static pressure, air velocity and flow readings Convenient colored hoses help proper interpretation of pressure readings Easy to use without sacrificing performance Bright, backlit display for clear viewing in all environments User-defined duct shape and size for maximum airflow accuracy Resolution down to 0.001 in H2O 99 point data storage capacity Min/Max/Average/Hold functions for easy data analysis Auto power off saves battery life 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 Airflow Meter Fluke FLUKE 922 Manometer Pressure Meter à¤Ã×èͧÇÑ´¤ÇÒÁ´Ñ¹ÅÁ à¤Ã×èͧÇÑ´ÅÁ
