The auto-ranging DSM-525 is a microprocessor scaler / ratemeter with a large digital display and separate inputs for 2 detectors. The DSM-525 has separate adjustable high voltage supplies for each detector. Each detector can have different dose and CPM calibrations. Inputs can have different functions, as well. 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; the cable is easily converted to USB with an adapter. Alarms are provided from 5 - 95% of full scale. Both probes can be connected simultaneously and only require adjusting selector switch for completely automatic operation. The most common combination of probes is the HP-265 pancake G-M probe with the MRSP-1 tissue equivalent scintillation probe. Most combinations of Johnson probes should work. You choose which two probes you want in the ordering process. If you only need one probe, we recommend the DSM-500 Survey Meter. Feel free to contact us if you require any assistance.
