Description: PINTUDY Digital Geiger Counter Nuclear Radiation Detector Beta Gamma X-Ray Meter Tester Analyzers Measurement Instruments 2019 Uses: suitable for indoor and outdoor or other carry to find radioactive sources; nuclear radiation detection; mining exploration; radiation measuring instrument; Avoid radioactive sources; detection of nuclear radiation intensity; radioactive radiation measurement of marble; Individual dose uranium and other radiation measurement and so on. Features: operation is very simple, a button to achieve a variety of work mode transformation handheld instrument design, built-in high-performance battery, suitable for outdoor carry The G-M counter is compensated and the energy response is improved detection of high sensitivity, especially for environmental radioactive monitoring and detection of micro-nuclear radiation Built-in probe type, effective protection of the probe is not damaged keep the count sound, can quickly determine the surrounding environment of the radiation, the rapid positioning of the exact location of the radiation source anti-interference ability, in the complex electromagnetic environment can work reliably instrument display accuracy up to 0.01Sv / h (CPM mode up to 1CPM) widely used, can be used for home environment, daily necessities, mineral rock, decorative stone and other radioactive detection can also be used for industrial or medical imaging equipment, radioactive leakage detection professional company design can give buyers a strong support Each instrument is calibrated with a source to ensure accurate and reliable measurement results The sale of radiation equipment to provide an annual free calibration service The Contrast of GMV2 and GMJ3 : GMV2 accuracy is industrial grade, J3 precision is the level of scientific research. V2 cover leather tube is built-in, J3 cover leather tube is an external split (split to facilitate the detection of holes or pit) The sensitivity J3 is higher than V2: J3 detects that the volume of the cover grid is larger than V2 (the volume of the cover grid is J3 is four times the volume of V2), so the radiation is passed through the volume, so the time ratio of the accurate radiation V2 is short, so the radiation value is smaller, the data is more smooth and stable. V2 accuracy of up to 0.02usv / h, is very high accuracy. J3 precision up to 0.01usv / h, is the highest accuracy. Selection Guide: Model: GMJ3 Host volume: 135 * 70 * 25mm Split cover leather tube volume: length 22cm, diameter 2.6cm Product weight: 240g 14500 lithium battery (1200mah) Uses: carry, industrial, home, strong radioactive research, medical use, can detect X ray Note: Please allow minor errors due to manual measurement.
