Glycerine Filled Pressure Gauges

Cotswold Engineering Supplies range of Gycerine Filled Pressure Gauges are used 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 for gases (except oxidising gases such as oxygen or acetylene) up to 25 bar maximum.

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.
