HDI Instruments, LLC ("HDI") was created in 1990 by William S. Condon, Harold J. Fenn, Richard C. McLathy and Jon D. deSilva, who with their combined experience of over sixty years in instrument design solutions, field service and sales saw a compelling need by the oil industry for accurate, reliable and environmentally safe monitoring instrumentation. The collaboration of these men resulted initially in the development of the HDI 2000 Pressure Sensing System, as 6" panel gauge system for choke panels and driller's cabins. These Systems remain the standard of the industry today. These internationally certified state-of-the-art Systems have led to evolutionary designs addressing additional applications such as the HDI 3200 Mud Gas Separator Monitoring System, the HDI 2250 Valve Position Indicator System and other advances in HDI's existing family of products. HDI has a 20-plus year field proven history with all major drilling companies across the globe. HDI owes its success to industry recognition that HDI manufactures reliable, accurate Systems that perform as specified. As HDI looks to the future, it will continue to provide the cutting edge technologies that will ensure the safety of its customers and provide accuracy and reliability backed by history proven results.
