The performance characteristics of the FD808 X-Gamma radiation measurement water finder:
1, the use of 16 bits up to 1MSPS ADC, can achieve zero leakage meter MCA design technology;
2, reading: dose rate shows sv/h, optional; cumulative dose sv; counting rate: CPS; quantitative calculation unit: ppm, ;
3, timed X-gamma spectral measurement, in the provision of dose rate at the same time, to achieve nuclide identification, but also quantitative calculation of radionuclide uranium, thorium, potassium content;
4, timing clock, massive storage, can save 2 million spectral data;
5, multi-layer menu display, automatic measurement and manual measurement mode selection and other functions;
6, the user customized measurement time, the instrument measurement after the completion of automatic calculation of dose results;
7, the use of rechargeable lithium battery power supply, with battery undervoltage prompt function, low-power design, convenient and fast;
8, power consumption: less than 160MW.
The main functions of the FD808 X-Gamma radiation measurement water finder:
