This gauge from RS PRO provides a clear, easy to read display of the pressure in a hydraulic or pneumatic system. It uses two needles – a black one to show the current pressure of the system and a red one that can be adjusted with a screwdriver to show the normal operating pressure. This allows the user to see at a glance whether the system is working correctly. It has a standard quarter-inch screw connection on the back to allow it to be connected to your existing pipes.
The gauge is designed to work with liquid or gas. The measurement is taken using a Bourdon spring which can be calibrated to ensure it stays accurate. It's suitable for use with any pressurised system, typically in industrial or automotive environments.
