Application

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.
