Product Description:

The YNSJ series mining double needle shock resistant pressure gauge is used to measure the pulse pressure in coal mines, and is used to measure the pressure and peak pressure of mechanical equipment under harsh environmental conditions. This instrument has small size, high accuracy, and shock resistance. The mining dual needle memory pressure gauge is based on the seismic (shock resistant) pressure gauge with a red needle warning indicator device added. The red needle can accurately record the instantaneous highest pressure inside the pipeline and stay at the highest position, while the black needle is only the current pressure. After the management personnel have made a record, the reverse time needle direction is turned back to the zero position, and the pressure is recorded again after being pressed up, so that the management personnel can make an early warning decision
