Guardian™ airflow monitors continuously check the face velocity of laboratory hoods and enclosures and alert the operator to airflows that drop outside preset levels with audible and visual alarms. The audible alarm can be muted at the touch of a switch.
The Guardian™ digital monitor displays actual face velocity on an LCD screen and includes a programmable switch to open the hood damper
The right fixture panel is factory-prepared for an airflow monitor on the following nonexplosion-proof laboratory hoods: Protector Premier™, Protector XStream®, Protector XL™, Protector Stainless Steel, Protector PVC, Basic™, and Fiberglass 30 hoods. On the ClassMate® hoods, the monitor can be installed in the front panel of the hood. On the Protector® Demonstration and XVS hoods, and the Protector® Workstation, the monitor can be installed on the top of the hood.
The Guardian™ 1000 digital monitor features an LCD of actual airflow in fpm or m/sec. from 0–999fpm. On the Guardian™ Jr. monitor, a green light glows when the velocity is normal. If the face velocity falls below setpoint for more than six seconds, the audible alarm sounds and the alert indicator glows red.
