LOW COST RADIATION MONITOR 
Detect Beta radiation and Gamma rays Designed for evaluation of ambient dosage of gamma-radiation, which can be done by common people in domestic environment (food products, construction materials, soil, etc.). Also, the instrument can be used by personnel, working with ionizing sources of radiation. Moreover, the instrument can detect objects, polluted by beta-active radioactive nuclides. The instrument uses the Geiger counter for calculation the amount of gamma- and beta-particles within 40 sec. and indicates the values in µSv/h and µRem/h on LCD screen. Registration of every particle is indicated by a sound-alarm, which makes it possible use “Search” mode. The instrument incorporates the following features: indication of value dimension, indication of sound-alarm threshold, continuous amendment of indications in proportion as duration of measurement increases, display illumination, MENU in English. CE. 2 year factory warranty.
