70mm 55 Bar Manifold Pressure Gauge Brass Connection Stainless Steel Pressure Gauge

70mm 55 bar Brass Connection Refrigeration Pressure Gauge for Manifold

Description

All gauges show gauge pressure, but some technical information (that of refrigerant manufacturers, for example) will refer to absolute pressures. So exercise great care when you consult this type of literature if you want to avoid making mistakes.

Remember that at atmospheric pressure (that is 0 bar on the gauge), liquid water evaporates at +100°C, liquid ether evaporates at +35°C and liquid R22 evaporates at -42°C.

Our gauge is calibrated for R22, the temperature scale therefore indicates -42°C, which is the temperature of evaporation of R22 at the pressure measured by the gauge (that is 0 bar gauge).

If the gauge had been calibrated for ether, say, then at 0 bar, the temperature scale would have shown +35°C.

Applications

Measuring refrigerant ammonia pressure and temperature

Suitable for corrosive environments and gaseous or liquid media that will not obstruct the pressure system
