The 4 Channel EGT Kit comes with a precision thermocouple amplifier and 4 type K thermocouples. The amplifier’s small size (3.35” x 2.15” x .650”) makes it perfect for motorcycle applications. The 4 Channel EGT Kit provides a highly accurate temperature measurement in range of 32-2282° Fahrenheit or 0-1250° Centigrade. It converts the thermocouple’s non-linear millivolt signal into a 0-5V linear analog output compatible with most engine management systems. It also has built-in cold junction compensation as well so any length wires can be used. Weld in 1/8 NPT bungs (P/N 1-0490) are not included in the kit but must be welded into the exhaust pipe of each cylinder for the thermocouples to screw into.
