Pressure gauge. This is a device that allows the monitoring of the pressure in a pipe system. The dial measures the pressure in bars. One bar is 100,000 Pascals (the standard unit of pressure), and is approximately equal to atmospheric pressure. The pressure here is measuring almost 200 bars (200 times atmospheric pressure).
