Precision Gauges

Introducing the Precision Pressure Gauges, a range of high-accuracy instruments designed for exact pressure measurement and testing of tanks, pipes, valves, and other industrial applications. Manufactured by IFG De Wit BV, these gauges are known for their reliability and precision.

Key Features:

• High Accuracy: Class 0.6 accuracy according to EN 837-1, ensuring precise pressure measurements.
• Durable Construction: Made with stainless steel AISI 304 and optional 316 SS for enhanced durability and corrosion resistance.
• Wide Range of Measurements: Available for vacuum, compound, and pressure measurements from 0-0.6 bar up to 1600 bar.
• Environmental Rating:
  • Dry execution: IP54
  • Liquid filled execution: IP65
• Versatile Applications: Suitable for various industrial environments, including those with vibrations and pulsations when using the glycerine-filled versions.
