The GE Druck DPI 104 is a microprocessor-controlled digital pressure gauge that combines precision and functionality in a compact, robust package. This unit is a 2 bar gauge (G) model, meaning it measures positive gauge pressure relative to atmospheric pressure, with a maximum working pressure of 2 bar.
