HIGH ACCURACY ALL-WELDED PROCESS SEAL GAUGE (MS9)

The Reotemp MS9 is a high-accuracy diaphragm seal developed primarily for low pressure applications. The MS9 offers improved temperature stability, critical for outdoor installations.

  • Extra-Large Diaphragm for High Accuracy, High Displacement, or Low Pressure Applications
  • Reduce/Eliminate Fugitive Emissions
  • Eliminate Potential Leak Points
  • Tamper Resistant
  • No Internal Gasket, Ideal for High Temperatures and Long Life
Accuracy With appropriate pressure range, seal gauge accuracy is gauge accuracy plus 0.5%. (May be subject to thermal error. Consult factory with questions.)
Ambient Limits -40°F/150°F
Process Limits with Diaphragm Seal -40°F/400°F (Direct Mount)*
