Compound Pressure Gauge is designed for precise measurement of both positive pressures exceeding atmospheric levels and negative pressures (vacuum) below atmospheric levels. Ideal for applications requiring accurate monitoring across a broad range of pressure conditions, it is widely used in industries such as oil and gas pipelines, water conservancy and hydro-power, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, electric power, marine vessels, machine tools, pipeline air supply, and vacuum equipment. By ensuring operational efficiency, safety, and compliance with industry standards, compound pressure gauges play a critical role in these sectors.
