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
