Accurate & Vibration-Resistant Pressure Monitoring
The Grow1 Liquid Filled Pressure Gauge is a commercial-grade pressure monitoring instrument engineered for accuracy, durability, and smooth performance in irrigation, hydroponics, plumbing, and agricultural systems.
Filled with liquid (glycerin), this gauge dampens system vibration, pressure spikes, and water hammer, ensuring steady, easy-to-read needle performance while protecting internal components from premature wear. With a versatile 0–100 PSI range, it is ideal for monitoring main water lines, pump discharge, filtration systems, and drip irrigation zones.
