Advanced Geiger counter DP 75 used in the Polish Army between 70s and 90s. In excellent visual condition - in the original box, with accessories and full instructions. This piece seems to be never used. Was tested and is in working condition. Device is designed to measure radiation in the range of 0.05mR/h - 500R/h. The device has 7 measurement sub-ranges. It also allowed for the indication of beta radiation with energy from 0.5 to 3 MeV in the activity range of 1000 rpm/cm². It signaled that the dose rate set at 20, 40, 80 and 100% of the upper scale of the meter was exceeded DP 75 is ideal for determining the gamma dose rate to a large extent, using two DOI-30 and DOI-80 tubes. *** Shipping within 3 days after payment is made.
