The 3.1 Dimmable Gauge is the latest & greatest version of our patented, thermally compensated, infrared belt temperature gauge design. This gauge allows for real-time monitoring of belt surface temperature, and features multicolor LED temperature alerts. On the anti-glare LCD screen you'll be able to easily monitor current, average, and high belt temperatures. Our added rocker switch now allows you to dim both the LED light as well as your LCD screen. Cycle between 5 levels of brightness to suit your riding needs! You will also have the ability to switch from Fahrenheit to Celsius if needed. Our thermally compensated infrared sensors are medical grade, and are manufactured to withstand the harsh environments found in motorsports.
