Post-Filter 100 psi Panel Gauge

Keep a close eye on your commercial RO system's performance with the Post-Filter 100 PSI Panel Gauge. This panel-mount pressure gauge provides clear, at-a-glance monitoring at the post-filter stage, helping operators verify proper system pressure and catch developing issues before they affect water production or damage equipment. It's a small instrument that delivers outsized peace of mind on a busy commercial skid.

The Eyes of Your RO System

Pressure gauges are the eyes of a reverse osmosis system. Monitoring pressure at the post-filter position lets technicians confirm the system is operating within its designed range and provides an early warning of fouling, restrictions, or pump trouble. A steady reading at the expected value tells you the system is healthy, while an unexpected rise or drop is often the very first sign that service is due, well before water quality or output suffer.

• 100 PSI range suited to RO post-filter monitoring
• Panel-mount design for clean integration into control faces
• Configured for systems with up to four 4" membranes
• Lightweight at roughly 1.05 lbs
• Replacement and upgrade option for commercial RO skids
• Supplied within the Water Softener Plus commercial RO options lineup

The panel-mount format is designed to fit cleanly into a control face for an organized, professional layout that keeps key readings together where operators can scan them quickly. Whether you're replacing a worn or fogged gauge, building out a new skid, or adding instrumentation to an existing four-membrane class system, this gauge integrates without fuss. Reliable pressure monitoring is one of the simplest and most cost-effective ways to extend the life of membranes and pumps, since it turns invisible problems into visible ones. For commercial RO installations that benefit from clear, dependable visibility into post-filter pressure, the Post-Filter 100 PSI Panel Gauge from Water Softener Plus gives operators the confidence to run their systems proactively rather than reactively.

Establishing a baseline reading when the system is new and healthy gives operators a reference point to compare against during later checks, turning the gauge into a genuine diagnostic tool rather than just a dial. Pairing post-filter pressure readings with other indicators, such as product flow and water quality, builds a clear picture of system health over time. Easy to mount and read, this 100 PSI panel gauge from Water Softener Plus is an inexpensive instrument that helps operators schedule service proactively and avoid costly interruptions.
