EGT Probe Exhaust Gas Temperature Sensor - For 2-Stroke Engines - 1/8" Diameter


Engineered for 2-Stroke Engine Applications!
• Probe diameter 1/8 inch (0.125 inch)
• Enclosed Tip Sensing Junction (Foul Proof)
• Response time constant: 550 milliseconds
• Includes 316 SS adjustable compression fitting

(Recommended for fuel types: Gasoline / Oil mixture)


The Exhaust Gas Temperature Sensor is specifically designed for use in 2-Stroke Engine applications. Made in the USA from superior materials. The Enclosed Tip sensing junction provides reliable measurement of temperature changes.

The Exhaust Gas Temperature Probe is capable of surviving extreme vibration and heat up to 2300 degrees F (1300 degrees C). The EGT probe is 0.125" diameter (3.175 mm) with a 90-degree bend to accommodate tight mounting locations. An adjustable (316 Stainless Steel) 1/8" NPT compression fitting adapter is included. The EGT probe cable lead length is 6 feet (1.8 meters) or 12 feet (3.6 meters).

IMPORTANT NOTE: 1/8" probes are not recommended for applications with high Exhaust Gas velocity or mounting pre-turbo (choose a 3/16" OD or 1/4" OD probe). Please confirm with your instrument manufacturer that the instrument is compatible with a Type K thermocouple sensor.
