SPD100 ElectronicsPersonal dosimeterAdopting a new type of PD detector, the instrument has the characteristics of wide measurement range, low power consumption, small size, and light weight, and can monitor the personal cumulative dose and dose rate caused by X and γ radiation. Both dose and dose rate data can be directly displayed and read out by LCD; The dosimeter can preset the dose and dose rate alarm thresholds arbitrarily, and can emit sound and light alarms when the thresholds are exceeded. It has under voltage indication and data storage function. You can choose to configure a data reader and computer management software to form a real-time personal dose management system. This instrument can be widely used in monitoring the cumulative dose and dose rate of individuals in nuclear power plants, nuclear factories, universities, research institutions, medical, environmental protection, customs and other departments, providing protection for the physical health of workers in the field of nuclear radiation. It is also suitable as a personal protective measuring device for residents living in areas with radiation risks such as nuclear power plants.
