Ashcroft 1134 Differential Pressure Gauge

The Ashcroft® 1134 differential pressure gauge is an economical means for measuring pressure between two independent pressure sources. Uses a convoluted diaphragm to measure very low inches of water differential pressure without migration between low and high pressure sides. 

Key Features:

  • Static pressure capability up to 35 psi
  • Superior magnets for smoother pointer motion
  • Standard with in-line and back process ports
  • Reed switches (optional) for direct system control


  • Accuracy: ±3% (ascending pressure)
  • Pressure Ranges: 0-0.6" IWD thru 0-60" IWD
  • Dial size: 4 1/2" only
  • Case: stainless steel
  • Body: glass-filled nylon
  • Wetted Material: glass-filled nylon, Teflon®, ceramic and various O-ring materials

The 1134 differential gauge is ideal where safe and reliable pressure measurement is essential:

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