Full-dial alarm warning
User-configurable minimum and maximum alarms can be set, with one of seven different colours assigned to each.
As soon as an alarm level is exceeded, the full dialface changes colour. If the level exceeds the alarm by more than 10%, the dialface flashes rapidly to further alert the driver.
With a choice of 7 user-selectable LED backlighting colours ( red, green, yellow, blue, purple, turquoise and white) the user can choose the optimum colour for maximum visibility and readability of the gauge, day and night.
Pro-control feature eg. built-in fan controller)
The Pro-Control feature activates low and high outputs whenever the user-defined alarm levels are exceeded. Pro-control outputs can be used to switch a relay to activate cooling fans, pumps, lamps, alarms, ignition kill etc.
Peak Recall
Press and hold the PEAK button to recall on the dial the highest temperature or lowest pressure or voltage since the memory was last reset.
Unrivalled accuracy
Precision stepper-motor needle movements and solid-state sensors ensure better than 2% accuracy.
