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 ambient 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.

AlphaGUARD incorporates a pulse-counting ionization chamber (alpha spectroscopy).
Through optimal geometry of the chamber and intelligent signal evaluation this radon monitor is suitable for continuous monitoring of radon concentrations between 2 – 2 000 000 Bq/m³.
The DSP (Digital Signal Processing) technology provides highly effective differentiation ability between “real” radon data and all kinds of artefacts.
