AlphaGUARD is suitable as a reference device and offers the following features:

Quality at the highest level
Long-term stable calibration factor (guaranteed 5 years)

Calibration traceable to different national standards (PTB, NIST, NPL)
Inbuilt quality assurance system for permanent validation of system operation and data

Fast transient response
Automatic background correction
No sensitivity to high air humidity

AlphaGUARD incorporates a pulse-counting ionization chamber (alpha spectroscopy).

Based on optimal chamber geometry 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.
