Air Alert 300 Face Velocity Airflow Alarm consists of a thermistor sensor mounted through the end wall of the hood, and a control monitor that gives both a visual and an audible alarm.

• Thermistor sensor and control monitor
• Visual and audible alarms

The alarm monitors fume hood face velocity and sounds the alarm when the airflow falls below safe levels

The Air Alert 300 operates on a 9 volt DC circuit and comes complete with an adapter that can be plugged into any 1290 VAC receptacle.

A glowing green light signals when conditions are safe again. The control monitor, which is mounted on the hood fascia, also contains a test/reset button that allows the hood user to verify alarm readiness.
