An exhaust gas temperature gauge (EGT gauge) is used to monitor the exhaust gas temperature of an internal combustion engine or rotary engine. By monitoring EGT, the user can get an idea of the air-fuel ratio. At a balanced air-fuel ratio, the exhaust gas temperature is lower than that in a lean or rich air-fuel ratio. High temperatures (typically above 1600 degrees F) can be an indicator of dangerous conditions that can lead to catastrophic engine failure.
