Gamma Radiation Monitors Model-P   arrow

Model-P
Purpose
The INC Model-P is a radiation area monitor designed to alert personnel to radiation exceeding selected levels. This alarm system provides indication of radiation levels at areas such as transportation  docks, storage sites, nuclear medicine facilities, laboratories, industrial centers and radiography installations.Description
When the radiation intensity exceeds a pre-set level, the green light goes out and the red light and buzzer begin to flash at a one second rate. The alarm is pre-set to trip at 2 mR/hr (user-adjustable). Both the high voltage supply for the Geiger tube as well as the low voltage power supply employs voltage regulation for maximum stability.

Adjustment
The sensitivity adjustment is the control mounted on the printed circuit board (screwdriver adjust). Turning this control CW increases the sensitivity. DISCONNECT POWER BEFORE REMOVING COVER OR ADJUSTMENT.

Wall Mount
Remove the cover and screw the hardware into the wall through the large mounting holes at each end of the box.

Spare Lamps
Two spare lamps and a spare fuse are located inside the alarm box.
