The Omega PGM-100L-30V15/-1/1BAR Liquid-Fillable Industrial Pressure Gauge is a highly reliable pressure and vacuum measurement instrument designed for sensitive fluid‑ or gas‑system monitoring in industrial and process-control environments. Engineered for applications requiring accurate low-pressure or near-vacuum readings, this gauge is well suited for HVAC systems, environmental control, chemical processing, water treatment, and vacuum pipelines. Its liquid-fill damping and durable construction deliver consistent, stable readings — offering peace of mind to engineers and system integrators working under variable operating conditions.
Key Features
-
Accurate pressure and vacuum measurement covering a range from –1 to 1 bar, ideal for sensitive control, vacuum systems, and low-pressure fluid monitoring.
-
Liquid-fill damping mechanism to absorb pulsation, vibration, and pressure surges — ensuring smooth needle movement and reliable readings even under dynamic or fluctuating conditions.
-
Robust, corrosion-resistant housing and internal construction designed for longevity and durability in industrial, chemical, or fluid-handling environments.
-
Clear, dual-scale dial (bar and psi equivalent) for flexible readability and compatibility with different measurement standards and international installations.
-
Easy installation and integration with standard industrial piping or vacuum systems — suitable for pipelines, tanks, environmental control units, and process instrumentation.
