Sealing Case Design for Stable Performance

One of the key strengths of the Standard Pressure Gauge WP is its sealing case construction, which helps maintain consistent performance under challenging conditions.

  • O-ring or rubber packing at joint sections helps maintain stable sealing properties

  • Internal structure is protected from dust and moisture

  • Suitable for use under rain and wet conditions (IP54 equivalent)

  • Proven internal mechanism based on long-established mechanical design

This construction improves reliability in environments where vibration, humidity, or temperature variation may affect standard pressure gauges.
