What Inkbird makes in our catalogue

Inkbird's ITC-308 is the plug-in controller many homebrewers use to turn a fridge or freezer into a fermentation chamber. It has separate heating and cooling outlets, high and low alarms and an adjustable compressor delay. One listing gives 110V, 10 A and 1100 W maximum; listings disagree on the load rating, so use the figure in your manual. The ITC-308 Wi-Fi adds app monitoring.

Other Inkbird models here: the ITC-608T dual-probe controller (ETL listed, up to 1800 W, 12 time periods), the ITC-308S with an IP68 stainless probe, a PID controller kit with a 40DA SSR for DIY brewing rigs, and the IHT-1P rechargeable instant-read thermometer.

Who Inkbird suits

  • Brewers building a fermentation chamber from a fridge or chest freezer
  • Keezer builders who need a thermostat override
  • Garage brewers who need heat in winter and cooling in summer

Tape the probe to the fermenter under insulation and use the compressor delay to protect the fridge.

Alternatives from other brands

If you want heat only, Eagle's FermWrap and Brewer's Best's Brew Belt plug into any controller. BrewBuilt's IceMaster glycol chiller suits conicals, and Kegco's HBK309S kegerator doubles as a temperature-controlled chamber.

More options in the summer brewing hub.

Before you buy

Add up the wattage of everything you plan to plug in, including the fridge's start-up and any heater, and compare it with the load rating in your controller's manual. Decide whether you need Wi-Fi alerts or a stainless probe for immersion, and keep the controller dry and off the floor.

Inkbird: questions

How do I use an Inkbird ITC-308 for fermentation?
Plug the fridge into the cooling outlet and a heat wrap into the heating outlet, set the target and differential, and tape the probe to the fermenter under insulation.
What is the Inkbird ITC-308 load rating?
Listings differ; one gives 1100 W at 110V (10 A). Use the figure in the manual that ships with your unit and don't exceed it.
Is the ITC-308 Wi-Fi worth it?
If you want alerts and readings on your phone, yes. Control is the same dual-stage heat and cool.
What is an alternative to an Inkbird controller?
A homebrew kegerator with digital control can double as a chamber, and glycol chillers suit jacketed fermenters. For heat only, a FermWrap or Brew Belt on a timer is not a substitute for a controller.
