The STC-1000 is a temperature controller you can use to control your fermentation temperature. It has a hot and a cool circuit which you can use to heat and ferment your wort depending on the setting of your controller. This is a bare bones controller, and you need to assemble the controller yourself.

The easiest way to do this is to buy two cheap extension leads which you can use for all wiring and plugs/sockets, and then assemble into any suitable housing such as a Systema box.

There are lots of easy to follow wiring videos available on Youtube.

Comes with a 1 meter long temperature probe.

Model -110V - 220V AC

This 30w Heating belt will gently warm without creating major hot spots on your fermenter. 
One reason to go belts over pads for the simplicity of adjusting the height of the belt on your fermenter to increase or decrease the heat transfer. 

Please note these belts are not designed to be used with Fermzilla's or thin plastic fermenters as they can cause warping.

Perfect heating solution for those who want more even coverage and absolute certainty that their PET fermenter will not melt even if the fermenter is empty.

Punching in at an ample 30 watts, this heating wrap belt is great when paired with insulation and a temperature controller box to dial in that optimum fermentation profile.
