DSM-525 Dual Probe Survey Meter

For Two External Probes

Detects Alpha, Beta and Gamma Radiation

DSM-525 dual probe radiation survey meter

Ideal for emergency response teams.

The DSM-525 is a digital scaler and  ratemeter with a large digital display and separate inputs for 2 detectors. The meter 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.
