(EN) Ultra-small continuous radon monitor
AlphaE is a versatile device for fast radon monitoring in buildings, outdoors or mines. Due to its light-weight and small dimensions, it can also perfectly be used to measure the personal radon exposure and to manage personal dose.
AlphaE is fast and accurate providing a first reliable measurement after 2 hours (faster response with higher radon levels). Low radon levels below 100 Bq/m³ (2.7 pCi/l) can be measured as specified by the latest World Health Organization (WHO) recommendations (12% uncertainty at 1 sigma/24 hours).
Up to 6 months battery life allows long-term measurement without mains power.
Permanent operations via mains supply are possible via USB port.
In addition to the radon concentration, the air temperature, pressure and humidity as well as the signals of the built-in tampering detector are simultaneously recorded, all accompanied by respective time stamps.
(EN) The reference instrument in radon monitoring
The new generation of AlphaGUARD offers high detection efficiency in radon monitoring, a wide measurement range (2 – 2 000 000 Bq/m³), fast response and permanent, maintenance-free operation with long-term stable calibration.
In addition to the radon concentration, AlphaGUARD simultaneously measures and records ambiant temperature, relative humidity and atmospheric pressure with embedded sensors. Optimal ergonomics, high responsiveness and a large digital display make AlphaGUARD a reference device to perform measurement and analysis everywhere from a lab to the field.
