EQF 3220 - Particle size specific Rn/Tn gas & daughters monitor
The EQF3220 is equipped with high-end semiconductor radiation detectors, both in the Radon measurement chamber and the detection head for the decay products. This allows a perfect separation of the different decay products of Radon, using alpha-spectroscopy. The measurement chamber works following the principle of high voltage collection and has, despite its low volume, an extraordinary sensitivity. This means a decisive advantage when it comes to measuring Thoron or small probe volumes. The long-term contamination that appears in other measurement principles by the increasing Pb-210 underground is completely annulated. There is no cross-sensitivity regarding the ambient radiation. The chamber is immune to humidity changes of the environment. The quality control is a main issue of any radiation measurement. Therefore the EQF3220 records a complete alpha spectrum for each measured value.
The EQF3220 disposes of a big touch-screen, showing the measured values. All measured data are stored in a 2GB memory card and are available from your PC or laptop through a USB interface. Data transmission and device control can be done by GPRS or GSM modems, as well as via ZigBee adapter (Wi-Fi). EQF 3220 comes with the latest release of the DVision software.
