2 1/2 Inch (63mm) Glycerine Filled Compound Gauge


63mm diameter glycerine filled pressure gauge for the measurement of fluid liquids that are not:

  • Highly viscous
  • High temperature (over 60°C)
  • Likely to solidify/crystallize
  • Corrosive to copper or tin alloys

Also suitable up to 25 bar maximum. For use in:

  • Pneumatics
  • Air compressors
  • HVAC industry
  • Water industry

Glycerine filled gauges are particularly suited to applications where oscillating / surging pressures or vibration are present. The damping effect of the glycerine will steady the pointer, making it easier to take a reading against the scale.
