The DSM-500 survey meter is digital, auto-ranging, and scaling. It requires an external probe that you can select below. The DSM-500 features 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. Adjustable alarms an optional external data port are also included. This survey meter supports most external probes. If you require a dual probe survey meter, we recommend the DSM-525.
