Contamination Monitor

The portable contamination monitor model CoMo 170 measures alpha, beta and gamma contamination with a high degree of sensitivity, utilizing a thin plastic scintillation detector of 170 cm² measuring area. A background subtraction function with adjustable background measurement time is included. The measuring results are presented on an illuminated large-area graphical LC display. The measurement is menu-prompted, and the measuring data are stored internally. The built-in RS232 interface and optional software make it possible to read and process the data. The monitor is operated by size AA batteries or by rechargeable batteries. The model CoMo 170 D additionally features a built-in GM detector for dose rate measurements in the range of 1 µSv/h … 20 mSv/h. For stationary use, two types of wall stations are available: a passive wall mount, which just accommodates the monitor, and an active wall mount, which includes a voltage supply. The optional mobile floor control device accommodates the contamination monitor for easy contamination checks of floor areas.
