Pressure Gauge

The Pressure Gauge is a high-performance, oil-filled instrument designed for precise and stable pressure measurement in refrigeration and HVAC systems. Its vibration-damping fluid minimizes fluctuations, ensuring accurate readings even in demanding operating conditions. Built with a durable stainless steel casing and a sensitive Bourdon tube, it offers excellent corrosion resistance and long-term reliability. With dual-scale pressure and temperature display and advanced sealing design, the gauge delivers consistent performance and enhanced protection against overpressure and environmental factors.

Features

  • Oil-Filled for Vibration Damping: Internal fluid filling effectively absorbs high-frequency vibrations from equipment, ensuring stable and accurate readings.
  • Enhanced Overpressure Protection: Reinforced design maintains measurement accuracy and minimizes zero drift under overpressure conditions.
  • Integrated Pressure–Temperature Scale: Dual scale display allows easy correlation between pressure and temperature for convenient operation.
  • Advanced Sealing Design: Optimized oil seal construction eliminates leakage risk and ensures long-term reliability.
  • Extended Service Life: Engineered for durability, providing consistent performance over an extended operational lifespan.
  • Customizable Fill Options: Available with glycerine or silicone oil based on specific application requirements.
