High Precision Pressure Gauge

Manufactured in compliance with EN837-1 standard, this gauge features full stainless steel construction and glycerin filling. With accuracy class CL1.6, it precisely measures pressure of low-corrosive, non-crystallizing, non-solidifying and low-viscosity liquid, gas and steam. Available in radial and back mount styles with multiple dial sizes and extensive pressure ranges. It delivers stable performance against vibration and impact, ideal for general industrial pressure monitoring.

Core Advantage

  • Superior Corrosion Resistance: Adopts 316/316L stainless steel for long service life under mildly corrosive working conditions.
  • Excellent Vibration Resistance: Internal glycerin filling cushions shock and vibration, ensuring steady pointer movement and clear readings.
  • High Measurement Accuracy: Accuracy class CL1.6 (±1.6% FS) guarantees reliable detection results.
  • Universal Connection: Equipped with standard G1/2M thread for easy installation and pipeline connection.
  • Diversified Mounting Options: Supports radial and back panel mount to fit various installation spaces and equipment.
  • Wide Media Compatibility: Suitable for liquid, gas and steam with low corrosivity.

Application

CDI liquid filled stainless steel pressure gauges are widely used in petroleum, chemical, oil refining, hydraulic system and laboratory industries. They are applied for real-time pressure monitoring on industrial pipelines, production equipment and test devices, and work steadily in vibration and mildly corrosive environments.
