A new detector technology defines a new level: outstanding sensitivity at dosimeter size. The instrument will not be affected by any variations of temperature and humidity, external radiation, mechanical shocks and vibrations. Two AAA batteries are good for several month of autonomous operation. These features as well as the additionally integrated sensors for temperature, humidity, barometric pressure and CO2 (both optional) making the Radon Scout Professinal the very first choice for both, short and long term Radon sampling, and for personal dosimetry. The fast and statistical accurate measurement allows – in combination with the optional switch output – the direct control of ventilation systems to maintain the statutory Radon threshold. Of course the instrument can be calibrated. All results are saved in the non-volatile memory and may be read through the USB interface. Only high quality components are used for the Radon Scout Professional which is manufactured at our company’s location in Dresden.
