ALL-WELDED PROCESS SEAL GAUGE

REOTEMP’s All-Welded Pressure Seal Gauge™ offers superior diaphragm seal safety and performance at an economical price. Combined with a gauge or transmitter, the tamper-resistant all-welded diaphragm seal reduces potential leak points, making it ideal for installations where process integrity and worker safety are paramount. Combined with PulsePlus™ protection, the Series MS8 can potentially triple the life of your gauge or transmitter.

  • Increases the Life of the Gauge by Up to 3x
  • Reduce/Eliminate Fugitive Emissions
  • Available Up to 5,000 psi
  • Eliminate Potential Leak Points
  • Tamper Resistant
  • Compliant to NACE MR0175, MR0103
