USER MANUAL
1 INTRODUCTION
The AlphaGUARD is the center piece of a professional portable measuring system
for the continuous determination of the radon and radon progeny concentration
in air, as well as selected climatic parameters. Depending on the model and
respective configuration, AlphaGUARD allows the user to differentiate
measurements of radon and thoron and to record simultaneously the radon
progeny concentration, as well as the gamma dose rate. The results of the
measurement operation which is controlled by real time clock are stored in a ring-
memory (first-in, first-out), to ensure that with continuous measuring operation the
last 60 000 data sets are always available and downloadableon a PC via USB, RS-
232 or Bluetooth interface.
The AlphaGUARD can be operated independently as well as with mains power
supply. The inbuilt rechargeable battery ensures an independent operation for up
to 10 days.
The AlphaGUARD uses the proven principle of the pulse ionization chamber (alpha
spectroscopy). AlphaGUARD impresses by its high detection efficiency for radon,
fast response to concentration gradients as well as maintenance-free long-term
operation. Also in extreme air humidity AlphaGUARD delivers reliable measuring
values and is insensitive to both vibrations and shock.
The radon progeny measuring head AlphaPM is a professional sensor front end for
recording of the airborne radon progeny concentration. The handy sensor unit is
applicable for long-term measurements (building examinations) screening
measurements or also in personal dosimetry.
For routine graphical work up, evaluation, archiving and presentation of the
measured data
DataVIEW PRO is offered as a comfortable, user-friendly
WINDOWS-compatible (7, 8, 10) PC software.
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 integrated pump allows radon and thoron measurements in flow mode. The
flow-regulated pump can be adjusted from flow rates of 0,05 l/min to 2 l/min.
