General Description
The Guardian Jr. Airflow Monitor is designed to continuously monitor airflow through fume
hoods. This permanently installed device provides both visual and audible alarms to alert the user
of abnormal airflow conditions. A green light on the front of the monitor indicates normal flow
conditions. When flow conditions lower than the set point are encountered, a red light is activated
along with an audible alarm.
A test button is provided at the front of the monitor to allow the user to check the operation of the
alarm.
Performance
The Guardian Jr. Airflow Monitor is designed for operation on all new non-explosion proof remote
and integral style Protector Fume Hoods. It is also set up for operation for both the new Basic 47
and 70 inch style fume hoods. The monitor itself is available both as a field installed kit or a
factory installed option.
