Digital Contamination Monitor (Micro) Type CM 710E designed, manufactured and supplied by Nucleonix Systems is a state-of-art, 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.
It has lot of unique features which include user interface, through a set of six command buttons & the visual indication to the user is on a 16x2 LCD dotmatrix 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 data communication software, through built-in RS232 serial port. |
Features
- Conforms to ANSI N42.17A performance specifications for Health Physics instrumentation (portable) &
 compliant.
- Microcontroller based design.
- Compact, Elegant and light weight.
- External probe with cover for Beta / Gamma selection.
- Measures doserate from 0-200 mR/h in 5 linear ranges.
- Measures dose rate in mR/h / mSv/h & countrate in cps/cpm.
- Accuracy +/-10% with Cs-137.
- Unit works on 7.5V, dry cells (5x1.5V)
- RTC for time stamp of each reading.
