Heavy-duty GPS instrumentation, multi-parameter display dashboards, and smart digital systems tailored for Uruguayan agricultural and logistics fleets.
Uruguay represents a strategic logistics hub for the Mercosur region. Backed by the vibrant Port of Montevideo and extensive transport corridors (such as Rutas 1, 3, 5, and 9), the demand for robust fleet instrumentation has climbed. Heavy-duty transportation, maritime commercial shipping, and industrial machinery require replacement and upgraded dashboards that can handle rugged terrains and high-salinity coastal conditions.
Standard 85mm instrumentation cutouts are the classic industrial benchmark. Legacy tractors used in local agricultural centers (like Paysandú, Colonia, and Soriano) frequently require conversion from failing mechanical cable systems to advanced, solid-state 85mm GPS speedometer-odometers. By using satellite-derived velocity telemetry, Uruguayan operators completely bypass calibration inaccuracies caused by varying tire pressures and customized gearboxes.
Similarly, the riverine logistics fleets along the Uruguay River and the Río de la Plata demand IP67-rated waterproof 85mm marine gauges. Saltwater mist and severe humidity cause conventional gauges to corrode rapidly. Our 85mm products feature anti-fogging curved glass, stainless steel bezels, and highly accurate stepper motors designed for marine applications.
