Aero Type Differential Gauge
Model Number J-2302

Indicate Positive, Negative, or Differential Pressures to within 2% Accuracy

The NEW! J-2000 Series Differential Pressure Gauges from Palmer Instruments feature a frictionless gauge movement. The magnetic element of the spiral movement has been eliminated and replaced with a rubber film, the sensitive component in measuring pressure. The J-2000 responds quickly to indicate low air or non-corrosive gas pressures, whether positive, negative (vacuum), or differential. The design resists shock, vibration, and over pressures without fluid fill - meaning no difficulties with evaporation, freezing, or leveling.

Flush or surface mounting styles, including connection fittings and instructions, are standard with the supplied mounting kit. Over 100 ranges are available in 6 measuring units for a wide variety of applications.
