      1143 Differential Pressure Gauge

      The Ashcroft 1143 differential pressure gauge is an economical means for measuring very low pressure with high static between two independent pressure sources. Uses a convoluted diaphragm to sense low inches of water differential pressure without migration of media between the low and high pressure sides.

      Key Features:

      • Glass filled nylon case
      • Easily removable window for wipe down
      • High static pressure capability (35 bar)
      • Superior magnets for smoother pointer motion
      • Reed switches (optional) for direct system control 


      • Accuracy: ±2% (ascending pressure)
      • Pressure Ranges: 0 ... 2.5 mbar to 0 ... 60 mbar
      • Dial size: 4 1/2" and 6"
      • Case: Glass filled nylon
      • Body: aluminum or stainless steel
      • Wetted Material: body material, Teflon®, ceramic and various O-ring materials


      The 1143 has an easily removable window for wipe down which makes it a perfect choice for locations where temperature fluctuations can cause condensation:

      • Liquid Level Measurement
      • Collector or Bag Filter Monitoring
      • Filtration Monitoring
      • Flow Measurement
