Description
Selection of Material, either Aluminium or Iron or Cast Iron or Copper is provided. In addition to these materials, user can add two more materials (of his choice) of different densities. User can enter material thickness between 0.1 mm to 999.9 mm. Backlit ON/OFF key allows user to turn OFF the backlit to enhance the battery charge. Backlit Time can be set as 1 or 2 or 5 minutes. Two line LCD display is used as interactive Menu for displaying Dose Rate in µR/Hr or Contamination in CPS or in Bq/gm and also to get the type of material and its thickness. Display of battery voltage and HV is also provided. No Pulse Alarm, Low Battery and HV Fail indications are also shown on LCD.
Calibration of PCM-3 is done at factory, using Co-60 radioactive sources supplied by BRIT, Mumbai. A small check source (Co60) can be supplied as an option at extra cost. Dose Rate Alarm setting is also provided to activate an LED indicator when the incident dose rate value exceeds the set alarm value.
Model PCM-3 is supplied with standard accessories like battery charger, operating manual and carrying case.
This pancake type GM tube is supplied externally with 1 meter long cable. Portable Radiation Survey Monitor, Model PCM-3, works on 6V rechargeable Ni-MH batteries. A mains operated charger is also supplied with PCM-3 for keeping the batteries charged. Typical operational battery charge life is 8 to 10 hours of continuous use.
