Fume hoods and biosafety cabinets (BSCs) require specific airflows to function properly. Low airflows risk loss of containment. This can have devastating effects, exposing occupants to hazardous chemicals or toxic substances.

The Alnor® AirGard® Laboratory Airflow Monitors continuously monitor fume hood face velocity or biosafety cabinet airflow. Audible and visual alarms warn users of potentially unsafe conditions if airflow drops. To enable remote monitoring, the monitors have a relay contact. AirGard Airflow Monitors are an economical solution, designed for stand-alone monitoring.

Laboratories around the world trust Alnor AirGard Laboratory Airflow Monitors.
