Description
The PRM is a capsule-type low-pressure gauge designed for measuring dry, non-aggressive gases such as air or nitrogen. It offers measuring ranges from 0–300 mmAq to 0–5000 mmAq, including vacuum and compound options. The case is available in iron or chrome-plated finishes, while the wetted parts use copper alloy. A zero-point adjustment mechanism is included to compensate for long-term drift. Available in 2.5″, 3″, and 4″ dial sizes, the gauge features acrylic or glass windows depending on size. The PRM is ideal for low-pressure ventilation systems, combustion air supply, filter monitoring, and general HVAC duct applications.
