XH-901 X-Ray Gamma Ionization Marble Material Radioactivity Tester Personal Dose Alarm and Nuclear Radiation Detector

design comfortable grip and edge skid resistance. Equipped with mountaineering buttons three foot supports various ways of wearing and convenient use on the work table. Simultaneous measurement of cumulative dose and dose rate shows that can also be displayed. Equipped with a unique LED lamp it can reflect the intensity of radiation according to the flicker frequency of LED. Predisposed dose rate and cumulative dose alarm threshold Random selection of sound vibration light and mute alarm mode. Automatically switch unit of measurement store data during alarm save cumulative dose and cumulative start date. Low design supply battery voltage status indication cumulative dose after failure can be kept for a long time. Real time clock function. After shutdown the clock operates normally. Built in fault detection dose rate overload alarm and protection function. Measurement range: Dose rate: 0.01 μSv/h - 150mSv/h; Cumulative dose: 0.00 μSv - 999.9mSv Energy range: 40Kev - 3.0Mev Energy response error: less than ±30% (relative to 137Cs) Relative basic error: less than 10% Measurement time: the measurement time is automatically according to the intensity of the rays and the response speed is faster. Alarm threshold: 0.5 1 2.5 10 30 50 100 500 Sv/h. Protective alarm response time: 3 seconds supply:2 x 1.5V AAA battery(Please note that we have to take the batteries due to the policy of the shipping company) low consumption background measurement can be used for 20 days (normal working time).
