Radiation monitoring instrument/environmental dose rate meter/radiometer (products that have passed metrological verification)

The X. gamma radiation air specific release energy (absorbed dose) rate meter is used for environmental monitoring, which uses highly sensitive and large volume NaI (Tl) crystals as detectors. It can be used for measuring extremely low radiation levels, measuring environmental gamma dose rates, searching for radiation sources, measuring the absorbed dose rates of environmental X - gamma external exposure air, using medical X-ray machines and 131I radiation measurement from Centers for Disease Control and Prevention (CDC) and health supervision agencies, nuclear materials, nuclear power plants, public safety and nuclear emergency, homeland security, military, customs and entry and exit inspection and quarantine, civil aviation, railways, highways and shipping, nuclear retirement and decontamination.

Radiation monitoring instrument/environmental dose rate meter/radiometer (products that have passed metrological verification)The instrument features an energy response that meets national standards and is equipped with a large capacity lithium battery. The battery level detector uses NaI crystal for real-time display, with high sensitivity and fast response speed. The measurement time can be selected, and the background light function can be set from 1 to 120 seconds as needed, making it convenient to use at night and in low light environments. The measurement unit is the internationally unified unit nGy/h (environmental level). Various alarm thresholds that meet national standards are available for selection, and the host can also define its own built-in detector to monitor the surrounding environment of the operator in real time. The large-sized dot matrix LCD display provides clear and intuitive display of measurement results; Touch sensitive buttons, easy and convenient to operate, can store 800 sets of data for viewing at any time, data printing, can communicate with the upper computer (can be equipped with analysis software), the host and probe connection cable can be extended up to 1.5 kilometers, and ZigBee mesh network wireless docking can also be carried out (optional). The host body is made of wear-resistant and corrosion-resistant high-strength aluminum magnesium alloy material, with a waterproof effect of IP65. The three legged bracket with free lifting configuration can store 800 sets of data from 80 detection points. The data storage methods include manual saving, automatic measurement saving, etc

Main technical indicators: NaI scintillator with a diameter of 50 × 50 (mm). The built-in detector of the host adopts energy compensation Geiger detector.
