Continuing with the evolution of our dual EGT-02 meter, Koso is proud to offer the dual EGT-02R with RPM and Water Temperature. This meter allows you to tune the engine more precisely and prevent engine damages. The settable warning and maximum recall functions for both EGT, RPM and Water temperature are easy to use and show you vital engine information. The color-changing backlight makes it very easy to see even at night. This cool instrument can save your engine from expensive repairs!

The settable warning for each cylinder gives you the opportunity to set a maximum temperature warning of up to 2,100 °F. The red flashing of the screen makes it very easy to see if something is going wrong with the engine. This Gauge could save your motor!
