These provide more precise control and many features not available with other controllers. All controllers are used to automatically fire a kiln or furnace. They convert this signal into a temperature and compare it with what was programmed.
All controllers work in essentially the same way.
The major difference is in a controller's reliability and how well its software allows you to precisely control the firing. They accurately control the firing and easily adapt to your needs. They can be upgraded in the future to add features. It does this using 2 thermocouples and special software that regulates the power to individual heating elements, adding heat where it is needed. This feature allows calibration using a self-supporting cone set near the thermocouple and it allows for a temperature correction to be entered into the controller to adjust the firing temperature, if needed.
