Weiss LF25S-2 Liquid-Filled Ammonia Pressure Gauge

Description:

The Weiss LF25S-2 Ammonia Gauge -30-0-60 PSI Liquid Filled 1/4" NPT Lower Connection is an industrial pressure monitoring instrument used in ammonia refrigeration and low-pressure process control systems. Commonly installed in refrigeration compressors, HVAC systems, cold storage facilities, industrial chillers, and ammonia-based cooling equipment requiring vibration-resistant pressure indication. Maintenance technicians, refrigeration contractors, and industrial system integrators use this gauge for system monitoring, replacement projects, and refrigeration equipment maintenance applications.

Applications:

The Weiss LF25S-2 ammonia gauge is commonly used in industrial and commercial refrigeration environments requiring accurate compound pressure and vacuum monitoring for ammonia-based cooling systems. It is frequently installed in food processing facilities, cold storage warehouses, refrigeration compressor systems, industrial chillers, ice production equipment, and HVAC refrigeration loops where liquid-filled construction improves readability and protects the gauge from vibration and pulsation.
