Guardian Jr. Airflow Monitor
The Guardian Jr. Airflow Monitor is designed to continuously monitor
airflow through enclosures. 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 is 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. To
temporarily mute the audible alarm, press and release the test/reset button.
