Here you will find radiation detectors of all known manufacturers (for example: S.E. International, Adafruit)
. Can compare prices and technical specifications (Headphone connectivity, Headphone out, Battery technology, Battery type, Battery life, Depth).
0.001-100 mR/hr, 0-350000 CPM, 0.01-1000 µSv/hr, 0-5000 CPS, LCD display, USB, 3.5mm jack, 9V alkaline, 273 g
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 (1.77 in.). Radiation symbol on front label and end panel marks the center of the detector.
Operating Range mR/hr - .001 (1µR) to 100 CPM - 0 to 350,000 µSv/hr - .01 to 1000 CPS - 0 to 5000 Total Counts- 1 to 9,999,000 counts Accuracy (Referenced to Cs137) Typically ±15% from factory, ±10% with NIST Source Calibration
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.
Selectable Alert Set Range mR/hr .001 - 50 and CPM 1 - 160,000. 70db @ 1m. Pulsating beeper sounds the alert. Adjustable alert levels are used for mR/hr / CPM, and µSv/hr / CPS. Alarm will sound when in Timer Mode when set alarm threshold is reached.
Anti-Saturation Meter will hold at OVER RANGE in fields as high as 100 times the maximum reading.
Averaging Periods Display updates every 3 seconds. At low background levels, the update is the average for the past 30-second time period. The timed period for the average decreases as the radiation level increases.
