The HDI Dual Race(DR) gauges employ the latest stepper motor technology for accuracy and fast response.
Our Dual display design shows both Bar and Psi in analogue (250degree sweep) and digital format which simultaneously provides an easy and precise
readout, in the shortest time possible.
The HDI DR gauges can also be used with an optional HDI-iDriver to record and recall the peak value as well as set warning values to trigger other deveices.
