Designed for evaluation of ambient dosage of gamma radiation, which can be done by ordinary people in domestic environment (homes, office, food products, construction materials, soil, etc.). Also, the instrument can be used by industrial personnel, working with ionizing sources of radiation. Moreover, the instrument can detect objects, polluted by beta active radioactive nuclides.<br>The instrument uses a Geiger counter to detect the amount of gamma radiation within 40 sec. and indicates the values in µSv/h and µRem/h on an LCD screen. Registration of every particle is indicated by a click sound, which makes it possible to quickly determine the location of hot spots.<br>Incorporates the following features: audio alarm with 3 adjustable thresholds, continuous updating of readout in proportion as duration of measurement increases, display illumination, MENU in English.
