9743204 Guardian Jr. Airflow Monitor

Requires cutout in the upper right portion of the ClassMate's front panel.

Guardian Jr. Airflow Monitor senses and alerts the operator to low airflow conditions. Includes face plate with circuit board, electrical power pack, vinyl tubing and airflow tube adapter. From the monitor's face plate, the user can easily select and calibrate a set point between 30 and 250 fpm using a velocity meter and screwdriver. If the hood's face velocity falls below the set point for more than 6 seconds, an audible alarm sounds and the ALERT indicator glows red. The TEST RESET switch, when pressed, mutes the alarm.
