The Exhaust Gas Temperature Sensor is specifically designed for use in racing, tuning, and testing applications. Made in the USA from superior materials. The Exposed Tip sensing junction provides immediate response to dynamic 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 will fit most internal combustion engine exhaust systems from approximately .750 inch diameter up to about 4 inch diameter with nominal installation modifications. The EGT probe is 0.187" diameter (4.75 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).

The probe cable is over-braided in stainless steel for heavy-duty abrasion resistance. The signal wires are FEP insulated. Designed to deliver high performance, high temperature measurements, reliably and consistently.

These high temperature sensors are the choice for professional racing teams, R&D test labs, and enthusiasts. The EGT probes can be used for many different applications, including Karts, Drag Racing, Formula 1, NASCAR, Off Road, Snowmobiles, Aviation, and Marine Racing.

IMPORTANT NOTE: Please confirm with your instrument manufacturer that the instrument is compatible with a Type K thermocouple sensor.
