Plus Internal GM Detector

The DSM-506 combined with the HP-265 PROBE gives the user great flexibility when surveying for contamination from alpha, beta or gamma isotopes plus the ability to survey for gamma dose rates up to 2000 mR/hr. The rate meter boasts an oversized digital display and has unique counts to dose capability allowing the user to quickly change from count rate to dose rate and back by simply flipping a toggle switch. Other features include a scaler for counts per unit of time, display error indications and audible/visual ALARMS.
