DSM 500 Series

The DSM-500 is a microprocessor-controlled instrument with an digital display and the capability for dual probe capability. Comes standard with timed-count capability, probe-saturation and error indicators. The DSM-501 is an internal 1" x 1" plastic scintillator that has a close to tissue-equivalent response and has an oversized digital backlit display, dose or cpm operation modes.The DSM-502 Survey meter is designed as the application for general users of radiation measurement and monitoring. The operation of the DSM-506 provides users the ease of an internal detector with the additional probe capability for those specific measurement needs. The DSM-525 has a dual connection capability that allows users multiple level measurements with as many as four different probes calibrated to each measurement type.
