KC761 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 KC761 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 KC761 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.

Usage field

The main function of KC761 is energy spectrum analysis. Based on this measurement, artificial radioactivity can be distinguished from background radiation, So it is possible to make an accurate judgment of nuclear contamination with KC761.
For example:
  • Identify whether soil, food, utensils, etc. are contaminated with gamma nuclides leaked from nuclear facilities.
  • To determine whether there is a leakage of nuclear reagents and medicines.
  • Identify the types of radioactive substances, such as identifying thorium, uranium, radium, 131Iodine, 137Cs, etc.
It can replace Geiger counter for radiation alarm and be used as daily monitoring of background and radioactive substances. Typical application scenes such as:
  • Radiation monitoring of stone, tile and other living environment items.
  • Security, accident investigation, production place monitoring.
  • Radiation diagnosis, treatment place monitoring.
