AlphaGUARD - Portable radon monitor
AlphaGUARD is a portable radon meter with high sensitivity, long time stable calibration (guaranteed for 5 years), outstanding accuracy and high storage capacity. Maintenance-free operation
It is the benchmark instrument for professional radon monitoring and accurate measurement on site in nuclear industry, health, research centers, construction and recycling sites, etc..
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.
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.
