Aeromist Liquid-Filled Pressure Gauge 0–2,000 PSI — 1-1/2" | Model: 57251

Monitor operating pressure in your high-pressure misting system with a gauge built to handle the vibration, pressure spikes, and outdoor conditions that standard dry gauges can't tolerate long-term. This liquid-filled pressure gauge uses glycerin fill to dampen needle oscillation caused by pump pulsation, delivering a stable, readable pressure indication even when the pump is running at full output. Without liquid fill, gauge needles in high-pressure misting systems oscillate so rapidly that accurate readings become impossible and internal mechanical wear accumulates quickly.

Rated from 0 to 2,000 PSI, this gauge covers the full operating range of 1,000 PSI Cat Pump misting systems with generous headroom above maximum operating pressure. The 1-1/2" dial diameter is compact enough for tight pump enclosures while remaining clearly readable. Center back mount configuration threads directly onto standard pump manifold ports via the 1/8" NPT male connection. Use this gauge to verify system pressure at startup, identify pressure drop caused by filter blockage, and confirm the pump is delivering consistent output across misting zones.
