Description Overview The GAO Tek gamma-ray radiation meter is specially designed to measure x,y radiation doses or rates in all kinds of radioactive working areas. In comparison with similar meters. This meter has a wider measuring range of dose rates. It has been widely used in hygiene departments, environmental protection, metallurgy, petroleum, chemical industry, radioactive laboratories, commodity inspection, etc. Features High sensitivity, wide measuring range good energy response High-speed low power consumption microprocessor Digital and gauge double display English interface display LCD digital display 800 group data can be saved Dose rate and total doses can be measured Alarm function (alarm function/choke/Detector failure) Battery Indicator Solid stainless-steel shell Technical Specifications Detector Φ30 × 25 mm, NaI Sensibility 1 µSv / h ≥ 350 CPS Energy Threshold Value 35 Kev Measuring Range Dose Rate 0.01 µSv/h to 500.00 µSv/h Accumulative Dose 0.00 µSv to 99999 µSv Energy Range 40 Kev to 3 Mev Energy Response ≤ ± 30% (relative to137Cs) Relative Error ≤ ± 10% Measurement Time 1 to 120 adjustable Alarm Threshold 0.25,2.5,10,20,60(µSv/h) Display Dose Rate µSv/h, µGy/h,µR/h(selectable) Accumulative Dose µSv Counting Rate CPS Power Source 1#battery (Two batteries) Power ≤ 120 mW (does not contain backlighting power consumption) Size 16.5 in x 9.1 in x 5.9 in (420 mm × 230 mm × 150 mm ) Weight 3.97 lb.
