AlphaGUARD – Radon monitor
AlphaGUARD is a portable radon monitor with high sensitivity and outstanding accuracy. It is the benchmark instrument for professional radon monitoring.
AlphaGUARD is a portable, battery or net-operated radon meter with a high storage capacity.
Thanks to its high sensitivity and long time stable calibration, this radon detector is the benchmark instrument for professional radon monitoring and accurate measurement on site.
In addition to the radon concentration in air, AlphaGUARD measures and records simultaneously the ambient temperature, relative humidity and atmospheric pressure with integrated sensors.
The complete product line provides all accessories for radon in air, water, soil, building materials, progeny, thoron and calibration equipment to perform air, water, soil and exhalation measurements. The collected data can be linked to the DataVIEW software, allowing data download and storage as well as professional data analysis and reporting. With AlphaGUARD, bring your Radon Lab everywhere.

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
