Internal Electric Contact Pressure Gauge

Internal Electric Contact Pressure Gauge

Product Description

    Model:PRE4.H

  • Contact material features: fire resistance,welding resistance, gold plating, oxidation resistance
  • The contact resistance is small, and the magnetic force can be adjusted for special use situations
  • The contacts are hidden behind the panel, which is not only visually beautiful,but also uses durable glass
