Duro United

Duro United Instruments is a subsidiary of Thuemling Instrument Group, an industry-leading manufacturer of high-quality gauges.

The foundation of Thuemling Instrument Group dates back to 1953 when Fred L Thuemling began his small sales company in Wisconsin, establishing a family-owned business.

Over the years the Thuemling organization has greatly expanded and divided into several brands, including Span Industrial Pressure Gauges, Fire Apparatus Gauges, Sub-Sea Gauges, and Duro United Instruments.

Duro United Instruments offers superior, rugged pressure gauges to fit any application. Standard Duro gauge dials range from 1.5” to 8.5”. With the accuracy of up to 0.5% and ranges of vacuum, compound, and pressure of up to 20,000 PSI, Duro devices will suit all your needs. Constructed with full-sized bourdon tubes (C-shaped and spiral) and mounted to precision German rack and pinion movements, Theumling’s Duro gauges are perfect for industrial applications.
