The Gauge on the right side is the Antipulsation Gauge and on the left is a normal gauge.
Pressure Gauges with severe pusation easily get damaged, have difficulty in reading pressure. The new Adarsh APDS Series Anti Pulsation Pressure Gauge is designed for such applications where there is severe pulsation. The unique design dampens the pulsation and makes for a better pointer reading and at that same time enchances the life of the gauge. Further there is no need of glycerin filling which is prone to leakages. The gauge is also protected from sudden pressure spikes or surges which are one of the major reasons for gauge damage.
