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.
The Fluke 922 was designed and built for how (and where) you do your job, with performance, ruggedness and ease of use, setting this Airflow Meter/Micromanometer apart from the competition. The bright white display and rugged holster and wrist strap allow you to take the meter 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.
Features:
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
