Gauge type and scale are important for accurate pressure monitoring and ease of use. Harris regulators typically feature large, dual-scale gauges (psi/kPa or psi/bar), which enhance readability and allow for use in different measurement systems. This is especially helpful for international or laboratory environments. For instance, the 401-250-350-D features 2" brass dual scale gauges, while the GP404-100-180 A comes with 1 1/2” dual scale gauges. This variety in gauge size and scale ensures you can select a regulator with the display that matches your workflow and visibility needs.
