WATCHMAN MANOMETER WITH ALARM
The instrument is designed for monitoring differential pressure in abatement area. Protective case contains pressure indicator/transmitter with LCD displays. Connected to a containment area by PVC tubing, it will monitor differential pressure in range of 0 to 0.100 WC and provide visual and audible alarm when differential pressure is less than 0.020 WC.
When alarm is acknowledged by pressing the Silence button, buzzer stops and the Alarm indication light changes from flashing to steady light as long as the alarm condition continues. System resets automatically when pressure returns to normal and is ready for the next alarm.
Can be used hung or table/desk mounted.
