General usage gauges for multiple applications where pressure or vacuum readings are required. Dampening helps reduce excessive needle fluttering making the gauge much easier to read. Internal components are compatible with many industrial applications. The ability to recalibrate the gauge is a standard feature on all gauges. The temperature scale reads in °F and pressure is displayed in either PSI or BAR. Metric gauges with a temperature scale that reads in °C and pressure is displayed in either PSI or BAR.
