Description
Data reads in a variety of formats ( µR/hr per hour, Counts Per Minute, µSv/h and Total Counts – with Timer) on the 128 X 128 color OLED display that measures 1.88 in. (47.9mm.) diagonally. In addition, ONYX is designed to share data through its micro-USB port. Twitter data are transferred using QR code displayed on the OLED in combination with a smart phone with a QR Code scanner.
Detector: Halogen-quenched Geiger-Mueller tube. Effective diameter 1.75″ (45 mm). Mica window density 1.5-2.0 mg/cm²; Detects Alpha, Beta, Gamma, and X-radiation
Operating Range: µSv/hr: .000 to 1,000::: µR/hr: .000 to 100,000 ::: CPM: 0 to 350,000 Accuracy: ± 10% typical; ±15% maximum Alert Range: 0 to 99,999 CPM; Beeper sounds the alert when warning level feature is activated Anti-Saturation: Readout holds at full scale in fields up to 100 times the maximum reading Audio: Beeper chirps with each count when Geiger Beep function is activated Averaging: Accumulate/Average feature builds average over time when activated
Count Light: Red LED flashes with each count Calibration: Cesium-137 (gamma from daughter metastable Barium) Gamma Sensitivity: 334 CPM per µSv/hr (3340 CPM per mR/hr) referenced to Cs-137 Efficiency: For 4 pi at contact Beta C-14 (49 keV avg. 156 keV max.): 5.3% Bi-210 (390 keV avg. 1.2 MeV max.): 32% Sr-90 (546 keV and 2.3 MeV): 38% P-32 (693 keV avg. 1.7 MeV max.): 33% Alpha Am-241 (5.5 MeV): 18% I-125: Smallest detectable level for I-125 is .02 mCi at contact
