Beijing Hua Ruisen Technology Development Co., Ltd. China Regional Sales: FH40G + FHZ672E-10 environment γ dose rate measurement system, Price: 205,000.00 yuan / Taiwan

, FH40G series is to monitor the γ-ray dose and dose rate portable detector designed its internal correspondence within the probe can accurately measure from natural background (about 100 nSv / h) to the highest value (1 Sv / h) range radiation dose. Powerful operating software and a range of the latest type of external probes can meet the highest requirements in the field of health physics. more for inspections in such areas as radiation.

FH40G series is a very easy to use digital measuring device for measuring dose rate and radiation pollution. Its versatile system can be completed almost all of the radiation protection measurements and meet various operational requirements. Number of external probes can be used with detector connection, α, β, γ irradiated measuring pollution levels affected area or employees and retain all calibration parameters. When connected FHZ 752 neutron detector in the mixed radiation field, it can simultaneously measure the neutron and γ radiation and two different levels of alarm can adjust FH40G + FHZ672E-10 environment γ dose rate measurement system to quickly and easily change or add detector function, especially in emergency situations even more advantages:
