Dosimeter DO111

Dosimeter is a device that measures either directly or indirectly, the quantities exposure, absorbed dose or equivalent dose, or their time derivatives (rates), or related quantities of ionizing radiation. Used in Surface radioactive pollution detection, Nuclear radiation detection, Molecular Biology, Suspicious object detection, Terrorism, Environmental Pollution Investigation, Stone Radioactive Measurement, Entry-Exit Commodity Inspection, Flaw Detection Also known as Radiation Dosimeter Features • Use efficient import MICA geiger detector. • Dose rate alarm threshold setting, super threshold alarm. • Flash and sound pulse frequency indicating radiation intensity. • Sound, vibration, light real-time clock alarm function. • Ultra-low power design battery real-time instructions. • Menu operation interface. • Unit shown CPM, CPS, Bq/cm2, mu Gy/h, mu Sv/h. • Adopts analog and digital display scale, more clear and intuitive. • Slide out detector protection and unique ray shielding plate. Specifications Temperature range: - 40°C to 50°C Humidity range: Relative humidity of 90% or less (40°C) Measuring range: Count rate 0~500000 CPM, 0~8000 CPS Radiation equivalent dose rate(EDR): 0.01 - 10000 uSv/h Agent sensors: Mica geiger counter, diameter: 45 mm Energy ranges of measurement: 25 KeV – 7 MeV Detection efficiency: Sr - 90 (546 KeV, 2.3 MeV beta Max) is about 75% of Am - 241 (5.5 MeV alpha) of about 36% Acuity: 3500 CPM/mR/h (for Cs – 137) Instrument background: 80 CPM or less Basic relative errors: 15% or less Power: 5 batteries or rechargeable batteries 2 section Power consumption: The machine current 8 ma or less Instrument (size and weight): 160x85x38 mm ; 0.5 kg
