Analog bar graph monitors air trends simultaneously with a digital display
Ideal for light commercial ventilation measurements
This digital balometer features a 24?x 24?hood opening to fit over standard-sized grilles and diffusers located on ceilings, walls or floors. The hood channels airflow through the base to directly measure air volume (CFM). Weighing less than six pounds, the balometer allows for single operator use and access into tight spaces.
Fast response LCD features an analog bar graph for monitoring airflow changes and displays digital readout. Measure air volume with or without hood connected to the balometer.
What included: NIST-traceable calibration certificate, and four C batteries.
