DSM-501 Digital Micro R Meter

This microprocessor-controlled instrument represents the new gold standard of MicroR survey instruments. The auto-ranging DSM-501 is a digital instrument with a large, four digit backlit, LCD that displays a precise reading with no user intervention required. The micro R meter includes an internal 1 inch x 1 inch plastic scintillation detector. The detector is tissue equivalent and can measure gamma at the microR level as well as detect some betas. This newer design of plastic scintillation provides more accurate dose measurements than meters utilizing the traditional sodium iodide detectors. The DSM-501 is equipped with over-range alarms, regular alarms and diagnostics. An RS-232 data output is available on request.

The DSM-501 Survey MicroR Meter is is recommended for nuclear power plant, health physics, and medical applications, or whenever dose measurement at the micro R level is required. This micro R survey meter is ideal for NORM measurement. Other applications include oil refineries and scrap metal facilities.
