Koso EGT-02R EVO – Dual EGT Data Logger with RPM and Water Temperature Display | Fast Response

With the EGT-02R EVO, Koso continues the evolution of its proven dual temperature gauge. Building on the popular EGT-02, this new model now adds RPM monitoring and precise water temperature display. This allows for finer engine tuning and reliable protection against damage.

Thanks to adjustable warning and maximum value settings for both exhaust gas temperatures (EGT A/B), RPM, and water temperature, you receive critical real-time data while driving. The user-friendly interface enables quick adaptation to individual needs – whether for tuning, racing, or everyday use.

A standout feature is the color-changing backlight, ensuring optimal readability even at night. This well-designed measuring instrument can be crucial in preventing costly engine damage.
