X-ray meters '' DP-3B '' and '' DP-3A-1 ''.

Dosimeters, radiometers, roentgenometers and other similar devices.The DP-3B and DP-3A-1 roentgenometers were presumably produced since 1985. The DP-3B roentgenometer is designed to measure the levels of gamma radiation on the ground. Installed on cars, airplanes, helicopters, diesel locomotives, river boats. The measurement range from 0.1 to 500 r / h is divided into 4 subranges. Power supply with a constant voltage of 12 or 26 volts. Preparation time for work 5 min. The mass of the radiometer is 4.4 kg. The DP-3A-1 roentgenometer is a modification of the main device and, apart from fixing and wiring external circuits, does not differ from it.
