压力表指示器 压力：0-150PA

For easy and quick measurement of the maximum peak pressure of engines.Consists of three major components: a check valve,a pressure gauge and an exhaust valve.The maximum peak pressure is directly read on the dial when the indication has settled.There is no need for diagram acquisition,area measurement with a planimeter,or length measurement with a scale.Oil-filled pressure gauges are used as indicators to provide outstanding vibration-resistant and heat-resistant characteristics.The internal pressure is released to zero by opening the exhaust valve after measurement.
