Specifications:
Riegler Pressure Gauges with a KL 1.6 accuracy class and a quarter-inch (G 1/4) thread are highly versatile Bourdon-tube analog instruments designed primarily for monitoring compressed air, non-aggressive gases, and low-viscosity fluids. The designation “KL 1.6” (or Cl. 1.6) indicates the Accuracy Class, which permits a maximum error of ±1.6% of the full-scale value.
Because Riegler manufactures this exact footprint across several variants (such as the budget-friendly “pressure line” series, plastic housings, or heavy-duty glycerine-filled housings), the generic technical specifications shared across the standard G 1/4 lineup are detailed below:
