DSM-525 DUAL PROBE SURVEY METER/SCALER

DSM-525 DUAL PROBE SURVEY METER/SCALER
W/ DIGITAL READOUT

The DSM-525 is a microprocessor Scaler/Ratemeter with a large digital display and separate inputs for 2 detectors. The 525 has separate adjustable HV supplies for each detector and each detector can have different DOSE & CPM calibrations. Inputs can have different functions i.e. Ratemeter on one input and Scaler on the other input. A threshold that is variable from 0– 100 % on the input signal eliminates unwanted signals below preset amplitudes. RS-232 data output is provided through 9 pin connector. Alarms are provided from 5 — 95% of full scale. Both probes can be connnected and only require adjusting selector switch to the probe for completely automatic operation.
