Temperature measurement units

Electronic kiln controllers represent the most significant advancement since the invention of the kiln itself. A controller controls, an electronic controller, controls tirelessly, accurately and without requiring continuous monitoring.

The digital "Set Point" controller is the simplest kind of electronic temperature controller available, but even it provides a quantum leap over non-controller based methods. The set point controller allows you to set a single "set" temperature and then have the kiln go to and accurately maintain that temperature until you shut it off.

Set Point controllers usually have a digital display which can show either the kilns current temperature or the desired set temperature. Your only interaction is if you wish to adjust the set temperature or end the firing. They are precise and will let you achieve the desired results consistently. A controller, even the simple will give you the kind of temperature control that you need to achieve desirable and repeatable results which are simply not possible without a controller.

The typical modern microcontroller and multi line character type LCD display allows personal computer like menu navigation and screens are presented in plain English. There is no need to try and figure out what to do next. It's on the screen and it's obvious.

Solid state for device management relays are more reliable and permit much faster cycle times resulting in greatly reduced temperature variation. An improved thermocouple interface system provides drift free accuracy, improved linearity and better reliability. A desktop sloped computer style enclosure makes programming the controller easier and more enjoyable and the stand alone system makes it easy to move between kilns.
