DA Series Radiation Monitors
The flexibility of the Rotem RAM DA Series can be expanded with a choice of nine external interchangeable detectors
suitable for alpha, beta, low or high-energy gamma and X-ray detection.
All detectors feature:
§ Simple plug-in digital interface
§ Automatic detector identification
§ Individual detector calibration factor stored within probe
§ Automatic unit selection according to detector
§ Optional extended cable lengths
§ Automatic detector self-diagnostic routines
Application: Measurement of gamma radiation over a very wide range. Based on different types of energy compensated GM tubes.Extended hook-up cable of up to 100 meters can be used.
Measuring Range:
GM-40: 250 µSv/h to 10 Sv/h
GM-41: 50 µSv/h to 1 Sv/h
