EGT-K is a precision thermocouple amplifier providing high accuracy temperature measurement in range of 0-1250°C. It converts thermocouple type-k non-linear milivolts signal to 0-5V linear (4mV/°C) output so it's compatible with most industrial applications and data-loggers. It has built-in cold junction compensation so any length wires can be used. EGT-K is available in single, dual or quad channel variant.
Perfect product, shipped pretty quick, works just fine with Megasquirt, it should work fine with anything as its amplifies EGT signal to linear 0-5V. I had a problem with VEMS amplifier, this one is much better and cleaner installation.
