RADEX RD1503+ Geiger Counter Radiation Monitor/Detector (0.05 ~ 999 µSv/h)

Reference: RADEX RD1503+ - Manufacturer: Quarta-Rad

Geiger counter
Detection of gamma, beta and X-ray radiation

graduated change of a threshold signal in the range from 0.10 to 0.90 µSv/h with an 0.10 µSv/h interval (available in individual settings);
evaluation of the radiation background dose rate (outside buildings) conforms with the Russian government`s instructions specified in «MU2.6.1.715-98» (Conducting a radiation-hygienic inspection of inhabited and public buildings. Methodical Instructions);
value of the background dose rate is saved even when the device is turned off;
display of the difference of the dose rate between the averaged and background values;
vibration signal is added as well as the audio alarm;
adjustment a of a vibration signal (on /off) is possible;
animation of the pressed command button (the icon of the button starts blinking on the display)

* Increased number of calculation cycles leads to higher reliability of indications. Two batteries with a capacity 1350MAh, at a level of a natural background no more than 0.3 µSv/h and with factory settings. * Characteristics are obtained due to research carried out by the Center of Ionized Radiation of the State Scientific Metrological Laboratory "VNIIFTRY " in the period from 1 to 8 December 2005 and confirmed by protocols of 14.12.2005.
