ERK-506

EMERGENCY RESPONSE KIT

The DSM-506 kit utilizes the DSM-506 Survey/Scaler meter to measure most alpha, beta, and gamma radiation & contamination fields frombackground to 2000mR/hr. An internal energy compensated GM detector,HP-265 GM pancake and the MRSP-1near tissue equivalent scintillator are connected to themeter and can have dual (dose or cpm calibrations) that are switch selectablefrom the front panel. The timed count scaler function makes low levelcontamination measurements more accurate once the operator selects the desiredprobe. Automatic ranging and diagnostics make the system extremely userfriendly. All components of the system are contained in a durable carrying casefor easy storage and portability.
