Description
The Compound Pressure Gauge is a precision instrument designed to measure both positive (pressure) and negative (vacuum) pressures in a single device. This dual measurement capability makes it ideal for applications where monitoring pressure variations is critical, such as industrial piping systems, HVAC networks, compressors, pumps, and chemical processes.
Constructed from high-grade stainless steel, brass, or alloy materials, the gauge features a robust bourdon tube mechanism that ensures accurate and reliable readings even in harsh conditions. Its durable construction resists corrosion, vibration, and mechanical shocks, ensuring long-term service life.
The gauge has a clear and easy-to-read dial with a pointer, allowing operators to quickly assess system pressure. The compact design allows installation in confined spaces and integrates seamlessly into existing pipelines.
Additional advantages include:
- Ability to monitor vacuum conditions as well as positive pressure
- High accuracy for safe operation of sensitive equipment
- Reduces the risk of overpressure or vacuum-related damage
- Suitable for a wide range of industrial, commercial, and HVAC applications
With these features, the Compound Pressure Gauge ensures system efficiency, safety, and reliability, making it an indispensable tool for pressure management in complex piping systems.
