JRP Digital Engine Water Temp Gauge Kit 52mm 0-120c

The JRP 52mm digital water temp gauge kit is an outstanding solution for monitoring your engine’s water temperature. These compact gauges pack a range of features that set them apart from many other aftermarket options. With a readout range of 0 to 120 degrees Celsius, they’re ideal for monitoring water temperatures in both the engine and radiator system of performance vehicles or off-road diesel 4x4s. These gauges are especially popular among our diesel customers, often purchased alongside our Boost and EGT gauges, as many diesel owners are particularly vigilant about tracking engine water temperatures.

These 52mm water temp gauges are part of our v1.5 LCD range and feature a function developed in-house at JRP called CPW. You can read more below about what makes this CPW feature such a useful and innovative addition to any temperature monitoring setup. Like all our 52mm gauge offerings, these sleek and stylish LCD units allow you to set a user-defined warning for high temperatures and also include a peak reading memory function—so you can check the highest temperature reached during a drive, which is valuable information for any performance or diesel setup.

Water temperature is definitely one of the key metrics diesel owners want to keep an eye on, and these compact gauges deliver the functionality and quality you’d expect from a high-performance product.
