The Omega PGM-100L-30V15/-1/1BAR Liquid‑Fillable Industrial Pressure Gauge is a precision-ready, liquid‑fillable pressure instrument engineered for accurate and stable pressure (and vacuum) measurement in industrial fluid and gas systems. Designed for applications where low-pressure, vacuum, or sub-atmospheric monitoring is required, this gauge offers smooth, reliable readings even under fluctuating process conditions — making it ideal for HVAC, vacuum systems, chemical processing, environmental controls, and other sensitive automation or process applications requiring dependable low-pressure measurement.
Key Features
-
Measures pressure (and vacuum) from –1 to 1 bar — suitable for vacuum to low-positive pressure systems in fluid, gas, or environmental control applications.
-
Liquid‑fillable gauge design that damps vibration and pulsation, ensuring stable, smooth needle movement and reliable readings in dynamic or vibration‑prone environments.
-
Corrosion-resistant, rugged construction to withstand industrial conditions, chemical exposure, or humid/vapor-laden atmospheres — ensuring long-term durability.
-
Clear dual-scale dial (bar and possibly psi equivalents) for easy reading and versatility across different unit standards.
-
Easy installation and compatibility with standard industrial mounting interfaces — suitable for pipelines, tanks, vacuum chambers, HVAC ducting, and process instrumentation systems.
