Electronics International CHT Instrument KitsElectronics International helped pioneer the digital engine instrumentation industry with our single and multi-channel EGT and CHT instruments. All of the instruments boast precise, one-degree (Fahrenheit) resolution. Also, every one of the instruments has a large, crisp LCD, viewable in direct sunlight and backlit for night operations. These instruments provide a straightforward, simple approach to engine analysis, while keeping a lid on purchase costs. If you ever desire to add channels to an existing Electronics International instrument, you can do so with the purchase of one of our Remote Switch packages.
