These can be used to control temperature of salt bath annealing pots, bullet casting pots, or almost any other 110VAC electrical heating appliance. Simply plug the control box into your wall outlet, then plug your pot and a thermocouple into the control box.
The device offers 3 control modes: PID, constant power regulation, and on/off. In PID and on/off modes, simply enter a target temperature and the controller will hold your pot within a few degrees. Constant power regulation lets you limit the output of a heater to a constant level regardless of temperature, and is convenient for controlling the vigour of a boil, for example when brewing beer.
