The air velocity monitor continuously monitors and indicates air flow velocity in the exhaust duct and displays important parameters. When the velocity or pressure drops below a predetermined level, an audible and visual alarm is activated. The monitor includes a high flow alarm to help detect excessive airflow.

This economical air velocity monitor is designed to alert you when air flow is too low or too high. A red LED light indicates low flow (adjustable from 0-150 FPM). A low flow audible alarm sounds, requiring manual acknowledgement to silence. A green LED indicates normal operation. A yellow LED indicates high flow (adjustable from 0-275 FPM).
