Product Barcode

The Alcor by Tempest 86252 is a grounded Type K Cylinder Head Temperature (CHT) thermocouple probe designed for use with compatible Type K CHT instruments and engine monitoring systems. Alcor specifically notes that Type K CHT systems are typically found in digital applications.

The 86252 uses a bayonet-style mount and is approximately 15 inches long. Its red and yellow leads are configured in a reverse stagger, with a long red lead and short yellow lead.

For most engine cylinders, the probe requires Alcor P/N 28202 bayonet adapter, which allows the probe to twist and lock into place with spring-loaded contact against the cylinder.
