The DSM-500 microprocessor-controlled survey meter represents is our newest line of digital survey meters. The DSM-500 includes a large, backlit digital LCD that automatically displays the correct reading with no user intervention required (auto-ranging). The DSM-500 can be configured to indicate, CPM, CPS, R/hr and/or Sv/hr. Units can be easily changed with an internal switch; no recalibration is required. The survey meter includes probe-saturation and other error indicators. A scaler function, adjustable alarms an external data port are also included. This survey meter supports most external probes. For a choice of probes with photos and specifications, scroll down for a list of probes. If you require a dual probe survey meter, we recommend the DSM-525.
