The Compound Pressure Gauge monitors vacuum and positive pressure in an engine's system. It consists of a dial face with dual scales connected to the engine's pressure system, which uses a similar dial mechanism to convert pressure changes into mechanical motion, which is then displayed on the dial. When the engine operates, the gauge provides real-time readings, allowing operators to monitor parameters such as intake manifold pressure, boost pressure, and any other relevant pressure-related metrics. The dual functionality of this gauge makes it a necessary tool for ensuring that the engine operates within safe and efficient parameters.Attributes:• Measures both positive and negative pressures, from -100 kilopascal to 100 kilopascal.• Features a large, easy-to-read dial with clear markings.• Dial can be rotated for easy viewing from different angles.Applications: The Compound Pressure Gauge is used to provide real-time monitoring of both vacuum and pressure within an engine system for maintaining optimal engine performance.
