Please call Rad Elec for pricing: 800-526-5482

 

AlphaGUARD - line :

AlphaGUARD - portable, battery- or net-operated radon monitor for the continuous determination of the radon- and radon progeny concentration as well as relevant climatic parameters and the gamma dose-rate.

AlphaGUARD incorporates a pulse-counting ionization chamber (alphaspec­troscopy) with high detection efficiency, wide measuring range, fast response to concentration gradients and perma­nent, mainte­nance-free operation. AlphaGUARD is insensitive to both high humidity and vibrations.

For the configuration and data transfer to a PC DataGATE is available. Connected with AlphaGUARD via RS-232 this processor-powered interface with integrated web server allows to integrate the monitor directly into local networks or to connect via remote data transmission to any location. For communication with AlphaGUARD via DataGATE any webbrowser (MS-Internet Explorer or Netscape) is sufficient.

For routine graphical work up and presentation, evaluation and storing of measured data DataEXPERT, a user-friendly Windows database with powerful software tools is offered.


AlphaGUARD P-Series - Record simultaneously radon con­centration and essential environmental air parameters (temperature, pres­sure, humidity) to explain the dynamics of radon concentration and their precise reasons. This way it is possible to draw valid conclusions regarding the temporal and spatial distribution of the radon gas. This is of significant benefit in radon mitigation. All P-models are fitted with a Quality-Control-System.

AlphaGUARD a versatile monitoring system:

The user of the AlphaGUARD PQ2000PRO disposes of a versatile monitoring system. This instrument configuration is the basis for the determination of the radon level of air inside or in the open, in soil gas,in water as well as for the radon progeny concentration and the equilibrium factor.

By equipping the AlphaGUARD PQ2000PRO with a Counter Module the user may also register TTL-signals (counter pulses) of external detectors. In particularly we offer the radon progeny measuring head AlphaPM, a newly developed device with very high sensitivity to connect to the AlphaGUARD PQ2000PRO. With this configuration the radon progeny concentration can be determined simultaneously to the Rn-222 level. The measuring values of the Alpha PM are also filed in the extended memory of the AlphaGUARD.

The ‘Overdrive’ Processor allows to operate AlphaGUARD PQ2000PRO in two alternative modes:

  • Diffusion mode with a 10 minute resp. 60 minute measuring cycle
  • Flow mode with 10 minute and 1 minute measuring cycle.

In combination with the particular accessories for soil gas sampling the flow mode enables qualified soil gas measurements up to continuous long-term observations. Due to its effective algorithms the flow mode is especially characterized for fast gradient functions. E.g. a fast and exact response of the radon monitor is also assured at changes in the concentration which happen very quickly and cover several decades. The decay time required by the AlphaGUARD PQ2000PRO between two consequent soil gas measurements is lowered to less than 5 minutes.

The AquaKIT set-up for the determination of radon in water is easy to handle and a field-suited method which allows fast and reliable direct measurement of radon in a closed gas cycle.

For the configuration and data transfer to a PC DataGATE is available. Connected with AlphaGUARD via RS-232 this processor-powered interface with integrated web server allows to integrate the monitor directly into local networks or to connect via remote data transmission to any location. For communication with AlphaGUARD via DataGATE any webbrowser (MS-Internet Explorer or Netscape) is sufficient

DataEXPERT a comfortable Windows data base software with professional software tools serves for the routine graphic presentation and analysis. It includes the reading of the progeny measuring values as well as a professional analysis and reporting. The operation is very comfortable and includes also the administration of the instrument-specific calibration factors of the radon progeny measuring heads, output of the radon progeny concentration as potential alpha energy [mWL, MeV/L and J/m³], automatic calculation of the adjacent equilibrium equivalent radon concentration (EEC) - in Bq/m³m, determination of the equilibrium factor (EF) as the quotient of the calculated EEC and the radon-222 concentration measured through the radon channel (i-chamber) of the AlphaGUARD PQ2000PRO.

The AlphaGUARD Monitoring System can be completed by further external sensors for the continuous registration of ambient parameters, for example differential pressure and temperature.

The necessary accessories are available for emanation measurements, repeated calibration as well as for the calibration of other active and passive radon detectors: radon sources, standard preparations, gastight measuring containers, etc. Please let us know your requirements!
