HydroLogic® Evolution-RO™ Quick Connect Liquid-Filled Pressure Gauge - 1/2in QC Tee - For Evolution-RO™ Systems

HydroLogic® Evolution-RO™ Quick Connect Liquid-Filled Pressure Gauge - Real-Time Pressure Monitoring for Your RO System

The HydroLogic® Evolution-RO™ Quick Connect Liquid-Filled Pressure Gauge enables real-time water pressure monitoring in your Evolution-RO™ system — an invaluable diagnostic and optimization tool for any serious hydroponic grower. Liquid-filled gauges dampen needle vibration for more stable, accurate readings compared to dry gauges. Installing this gauge lets you monitor inlet pressure, identify pressure drops caused by clogged pre-filters, and verify that your system is operating at optimal pressure for maximum RO output and TDS rejection. Installs easily via the included 1/2in quick connect tee fitting.

Key Features & Benefits

• Liquid-filled for stable readings: Glycerin-filled gauges dampen vibration and pressure pulsation, providing steady, accurate pressure readings compared to dry gauges.
• Quick connect installation: 1/2in QC tee fitting allows tool-free installation into the Evolution-RO™ system plumbing at the appropriate monitoring point.
• Real-time pressure monitoring: Lets you verify system inlet pressure, identify pre-filter clogging (pressure drop indicates it's time to replace the filter), and confirm your system is operating in the optimal pressure range for your target GPD output.
• Optimizes system performance: Knowing your system pressure allows precise decisions about booster pump use, filter replacement timing, and expected RO output.

Who Should Use This

Recommended for any Evolution-RO™ operator who wants visibility into system pressure for performance optimization and proactive maintenance. Particularly valuable in commercial facilities where consistent RO output is critical to daily operations.

Compatibility

For use with HydroLogic® Evolution-RO™ Systems. Connects via 1/2in quick connect tee fitting.

Frequently Asked Questions

Why use a liquid-filled gauge instead of a dry gauge?

Liquid-filled gauges contain glycerin that dampens needle vibration from pressure pulsations in the system, resulting in more stable and easier-to-read pressure readings — especially important in systems with pumps or variable flow.

Where should this gauge be installed in my RO system?

For most useful diagnostics, install the gauge at the system inlet to monitor incoming water pressure. Consult HydroLogic® for specific recommended installation points for your Evolution-RO™ configuration.

How does pressure monitoring help with maintenance?

A decreasing inlet pressure reading typically signals a clogged pre-filter or sediment filter — allowing you to schedule timely filter replacement before it significantly impacts RO output or membrane performance.

What PSI range should my Evolution-RO™ operate at?

Optimal operating pressure varies by system configuration. Generally, higher inlet pressure within the system's rated range improves GPD output and TDS rejection. Consult the Evolution-RO™ 1000 manual for recommended pressure ranges.
