The HDI Pressure Gauge is the product HDI was founded on. The HDI 1000B is our latest battery-operated cornerstone product; it is an intrinsically safe, certified, solid-state electronic pressure gauge primarily used for choke console applications. It is easily readable regardless of the lighting conditions. HDI routinely builds, installs, and services custom HDI 9000 Choke Console Systems designed with HDI 1000B gauges, but the 1000B can also be purchased to retrofit standard 6” hydraulic gauges or for OEM use. HDI additionally offers stand-alone monitoring systems with the 1000B – anywhere the user needs a primary or secondary (slave option available) display. This model offers pressure ranges up to 16,000 psi with accuracy of 0.5% of full scale. Each 1000B is comprised of a Gauge Display, Inline Cable, and Sensor Assembly allowing the display to be close or far from the connection point. It has been used in the field for over 25 years and is based on HDI’s 25 year field proven platform. All HDI Gauges provide safety, accuracy, reliability, and low maintenance for the user.
