Houston Digital Instruments, based in Houston, Texas, provides instrumentation for the oil and gas industry. The company traces its origins to the early 1990s, when major operators urged the development of a safer, more accurate alternative to hydraulic pressure gauges. By 1991 it field-tested the HDI 2000, a six-inch panel gauge, and its successor, the HDI 2000B, is used in offshore well-control applications by international operators and drilling contractors. Today, the firm offers certified, intrinsically safe instrumentation for surface monitoring in high-pressure, high-temperature oil and gas environments, and it serves a global customer base as a mid-sized company. Its product range includes pressure gauges, pressure transmitters, pump stroke counters, and choke position indicators, with emphasis on safety and reliable performance.
