Yunyi Jy Hydrualic Dead Weight Tester Pressure Calibrator
Description Yunyi Jy Hydrualic Dead Weight Tester Pressure Calibrator
JY series piston gauge is our new R & D product manufactured
according to the latest national "piston gauge" test procedures
(JJG59-2007). The key components of piston gauge uses a tungsten
carbide material with a high hardness and low
temperature coefficient of linear expansion, which improving the
wear resistance of the piston,therefore only a little (negligible
)deformation under the pressure,performance is extremely stable.
Working medium with a piston isooctyl sebacate,
so pressure gauge with high sensitivity.
As a result of new materials, new technologies, new processes,the
technical indicators of new piston gauge has been greatly improved.
Thus widely used to test digital pressure gauge, precision pressure
gauges, pressure transmitters, pressure sensors and other pressure
instruments.

Applications Yunyi Jy Hydrualic Dead Weight Tester Pressure Calibrator
As the most important pressure reference instrument, the piston
pressure gauge is mainly used to calibrate other pressure
instruments. It is one of the pressure reference instruments and
the most cost-effective pressure reference equipment on the market.
The piston pressure gauges produced by our factory are not only It
is our market positioning for piston pressure gauges that it is
limited to obtaining the national verification certificate,
focusing more on the convenience of measurement use, and making the
measurement efficiency higher and easier.
