About Items:

1 (one) new RFT (DDR) Geiger-Muller G-M beta adn gamma Counter Tube V-AZ-114NR  (military markings - 70014.NR).

Condition:  These Tubes ware made by military plant in former DDR.  New tubes, in original box directly from the factory. Surplus of military equipment, only in great condition. New, old stock. Best quality!

RFT (DDR) made glass Geiger Mueller tube is designed to detect beta and gamma rays.

The counter are designed to be operated in various dosimetric and radiometric devices.

Dimensions of the V-AZ-114.NR (70014.NR):

Length of lessons                              54 and 44 mm (2.13 and 1.73 inches)

Electrical characteristics:

Working Voltage  (tested)                  350 – 475 V

Operating Voltage  (tested)                400 V

Plateau Length  (tested) >                  80 V

Unfortunately we do not have the technical characteristics of the V-AZ-114.NR.

We know only that they approximately coincide with those of the SBM-20 as in the production of military product SBM-20 had shown a lack of security and were replaced with V-AZ-114NR.

Shown below are characteristics of SBM-20!
