Ashcroft 1131 Differential Pressure Gauge

The Ashcroft® 1131 differential pressure gauge is an economical means for measuring pressure between two independent pressure sources. Uses a rolling diaphragm design to separate high and low pressure ports and isolates media between low and high pressure sides.

Key Features:

  • High static pressure capability (up to 3,000 psi)
  • Superior magnets for smoother pointer motion
  • Reed switches (optional) for direct system control 


  • Accuracy: ±2% (ascending pressure)
  • Pressure Ranges: 0-5 thru 0-150 psid
  • Dial size: 2 1/2", 3 1/2", 4", 4 1/2" and 6"
  • Case: stainless steel
  • Body: aluminum, brass or stainless steel
  • Wetted Material: body material, Teflon®, ceramic and various o-ring materials

The 1131 differential gauge is ideal where safe and reliable pressure measurement is essential:

  • Filtration Monitoring
  • Flow Measurement
  • Leak Detection
  • Clean Room Positive Pressure (low dp)
