Water/food radioactivity detector
The BG9711 mineral and water radioactivity detector is used to measure the specific activity of 137Cs and 131I radioisotopes in minerals, food and water (including various beverages). It is used for households, enterprises, shopping malls, inspection and quarantine, disease control, environmental protection, etc. An ideal instrument for institutions to quickly detect the level of radioactive contamination in food or water. The instrument uses a scintillation crystal detector, which has the characteristics of high sensitivity and fast response. The shell of the instrument is a metal integrated structure, with LCD information display and function keys, and the operation is simple and easy to understand. It adopts 100～240V AC power supply, and can also install two AA batteries as a backup power source, which is convenient and flexible and suitable for on-site testing occasions.
Features:
◎Single-chip microprocessor data processing and storage, LCD directly displays radioactivity and specific activity;◎Maximum 200 groups of historical data query;
◎Three-color indicator light informs the degree of radioactive danger;
◎Functional soft key design, screen prompts for operation steps, easy to understand;
◎Built-in micro battery, the internal clock can continue to run after the power is off, and the setting parameters will not be lost;
◎Equipped with an electronic scale and a special measuring cup, which can measure liquid beverages and solid food;
◎Full metal shell, built-in lead shielding layer, effectively isolate external radiation interference;
◎Dual power supply of AC and dry battery, which can be used indoors or when carried out;
◎The optional USB interface is connected to the PC, the operation of the instrument is controlled by the software, and the measurement results are stored or agreed.
