Digital Contamination Monitor ** [ TYPE : CM 710N]
Digital Contamination Monitor Type CM 710N designed, manufactured and supplied by Nucleonix Systems is a state-of-art, ruggedized microcontroller based unit which essentially serves as a low level alarming survey meter cum Beta contamination monitor. It measures contamination in CPS or CPM mode and low level gamma dose rate in mR/hr / µSv/h.
Pancake Configuration offered in Internal or either in External.
It has lot of unique features which include user interface, through a set of seven command buttons & the visual indication to the user is on 16×2 LCD dot matrix display module. This unit has preset alarm facility which can be set throughout the range of the instrument.Unit can store upto 1000 readings and stored data can be downloaded into PC using communication software, through built-in Micro USB port.

Serves as a low level contamination measuring unit to check for ß & λ contamination in CPS,CPM modes, in Nuclear & Radio logical facilities ,Radiotherapy & Nuclear medical depts., PET-CT centres, medicine cyclotrons etc. It can also measure low level gamma dose rates at these facilities
Contamination of hands, clothing, work areas, flooring, surface contamination of source housings, surface, ports of therapy machines, industrial sources etc., can be measured.
