SK7761 is a radiation multimeter based on spectrometer analysis, featuring a scintillation detector as its primary sensing element and an integrated multi-channel analyzer. Through spectrometer analysis, it accurately identifies the energy and intensity of radiation, providing much richer radiation measurement information compared to Geiger counters.
With no consumable parts, the SK7761 offers access to all measurement functions without the need for a connected smartphone. Powered by replaceable AA batteries designed for a storage life of up to 10 years, it’s ideal for long-term storage and emergency use scenarios. It boasts comprehensive external interfaces, supporting Bluetooth and Ethernet connections, and can be powered via Power over Ethernet (PoE), enabling the formation of sensor networks for long-term online monitoring. For enthusiasts of nuclear physics, the SK7761 can output pulse signals via a 3.5mm jack to connect with a extend analysis system.
Designed with a rugged and flame-retardant shell, it’s suitable for outdoor applications such as exploration, scientific expeditions, accident investigations, and more. It operates reliably within altitudes ranging from -2000m to +30km, and even in vacuum conditions. With an IP65 waterproof rating and the ability to float if dropped in water, it’s built to withstand various environmental challenges.
Application
The main function of this instrument is energy spectrum analysis. Based on energy spectrum analysis, the nature of radiation can be clarified, and trace amounts of artificial radioactivity can be distinguished from background radiation, so as to make an accurate judgment on nuclear pollution. For example:
(1) Identify whether soil, food, utensils, etc. are contaminated by γ-nuclides leaked from nuclear facilities.
(2) Determine whether there is a nuclear reagent or drug leak.
(3) Identify the type of radioactive material, such as thorium, uranium, radium, 131 iodine, 137Cs, etc.
It can replace the Geiger counter for radiation alarm and be used for daily background and radiation material monitoring. Typical application scenarios include:
(4) Radiation monitoring of stone, tiles and other living environment items.
(5) Security, accident investigation, and production site monitoring.
(6) Radiation diagnosis and treatment site monitoring.
It can be used as a teaching instrument or for specific scientific research purposes.
