The GE Druck DPI 104 (now manufactured by Baker Hughes) is the industry standard for reliable, high-precision digital pressure measurement. This model is calibrated for a 3000 PSI (200 Bar) range, making it perfect for high-pressure hydraulic systems, pneumatic testing, process monitoring, and panel mounting. Unlike analog gauges, the DPI 104 eliminates parallax error and provides instant, repeatable readings.
