IMI Inspector BLE Inspector alert detects radiation (CPM: 0 to 350,000)

Sensor: Halogen-quenched Geiger-Mueller tube. Effective diameter 1.75″ (45 mm). Mica window density 1.5-2.0 mg/cm²

Display: 4-digit liquid crystal display with mode indicators

Accuracy: ± 10% typical; ±15% maximum

Alert: µSv/hr: 0 to 500; mR/hr: 0 to 50; CPM: 0 to 160,000; Beeper sounds the alert

Anti-Saturation: Readout holds at full scale in fields up to 100 times the maximum reading

Audio: Beeper chirps with each radiation event (can be muted)

Averaging Periods: Display updates every 3 seconds, showing the average for the past 30-second time period at normal levels. The averaging period decreases as the radiation level increases.
