Specifications

Detector
Internal Halogen-quenched, uncompensated GM tube with thin mica window, 1.4-2.0 mg/cm2 areal density. Effective diameter of window is 45 mm (1.75 in.). Radiation symbol on front label marks the center of the detector.
Display
4 digit liquid crystal display with indicators.
Averaging Periods
Display will update every 3 seconds. At low background levels, the update is the moving average for the past 30-second time period. The timed period for the moving average decreases as the radiation level increases

Energy Sensitivity Detects Alpha down to 2 MeV.Detects Beta down to .16 MeV; typical detection efficiency at 1 MeV is approx. 25%. Detects Gamma down to 10 KeV through the end window. 3340 CPM/mR/hr (Cs137). Smallest detectable level for I125 is .02 µCi at contact. Operating Range mR/hr - .001 (1µR) to 100 CPM - 0 to 350,000 µSv/hr - .01 to 1000 CPS - 0 to 5000 Total/ Timer - 1 to 9,999,000 counts Accuracy mR/hr ±10% typical (NIST), ±15% max - 0 to 100 µSv/hr ±10% typical (NIST), ±15% max - .01 - 1000 CPM ±10% typical (NIST), ±15% max - 0 to 350,000 (Referenced to Cs-137)

Alert Set Range mR/hr .001 - 50 and CPM 1 - 160,000. 70db @ 1m. Count Light Red LED flashes with each radiation event. Audio Indicator Internally mounted beeper (can be switched off for silent operation) Outputs Dual miniature jack drives CMOS or TTL devices: count to computer or datalogger. Submini jack input allows for electronic calibration Anti-Saturation Meter will hold at full scale in fields as high as 100 times the maximum reading. Power Requirements One 9-volt alkaline battery.
