Deep borehole device zPas-10M-28-100-0,015-150 for hydrodynamic studies in oil and gas wells. It has an internal memory of up to 8 million records of values.
It is powered by a battery with a battery life of up to 250 days on a single charge. In comparison with classical sapphire devices used in the Russian Federation, zPas devices have a sensitivity of 10 Pascal, which is an order of magnitude higher.
Also a very important indicator - stable operation of quartz resonator in several times, not requiring calibration for a long time
