Portable Contamination Monitor CoMo 170 / CoMo 170F with thin-layer plastic scintillation detector for highly sensitive measurement of α-, β- and γ-contaminations.
Technical Features
An essential advantage of the CoMo 170 / CoMo 170F is the detector technology, which completely works without gas filled or gas flow proportional detectors, using a thin-layer plastic scintillation detector with ZnS-coating. So it is possible to perform α-, β- and γ-measurements with only one detector. No expensive costs for consumable gas or for the repair of Xenon detectors. Replacement of a defective foil can be effected by the user himself.
- Indication of measured values either in cps or nuclide referred Bq and Bq/cm², digital and analog (bargraph) indication of measured values
- the measuring system automatically identifies the existence of α-radiation
- calibrated nuclide file, free extensible (user-specific nuclides can be added)
- settings and important measurement parameters are secured by a code word
- data storage
- integrated calibration software
- possibility to connect external detectors, e.g. for dose rate measurement, automatic detector identification
- serial interface RS232 for PC system
- stationary use in wall station (option) with power supply
