The HDI M100 Pressure Gauge is a solid-state electronic pressure gauge primarily used for standpipe, pumping, and cementing measurement applications. The HDI M100 is used where indication at the point of measurement is a must and the ability to handle high vibration and harsh environments is crucial. It is easily readable regardless of the lighting conditions. This model offers pressure ranges up to 16,000 psi with accuracy of 0.5% of full scale.

It has been used in the field for over 10 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.
