Inkbird ITC-308S Temperature Controller Digital Thermostat Controller with 1.97 Inches Replacement NTC Probe for Heating and Cooling

Very good product, I use this with a heat pad, and a home made insulated box for fermenting beer. This inkbird controller is much better than the previous controller I had and offers control for both heating and cooling. It has very accurate control perameters, and is easy to use and set, with a detachable heat probe.There was also a good deal on when I bought it and managed to get a discount with Amazon as well, so it turned out to be excellent value for money.I only use mine for heating on my set up as I don't currently have any additional space for making a dual fermenting chamber from a fridge.

In a nutshell this device will keep your fermentation at the right temperature with no intervention from yourself. It does this by monitoring your fermentation with a temperature probe and switches the power on and off to either the heater or the cooler socket depending on your set-up. You can choose from two different length probes when you purchase the unit a 2" or a 12" sensor, the length refers to the stainless steel tip.In the UK particularly in winter, the unit will only be switching the power on and off to your heater. In my case the temperature of the unit is to set to 23.5C with a permitted variance of +/-0.5C. The fermentation bucket or carboy is sat on a heat mat; inside the bucket or carboy I place a stainless steel thermowell stopper (purchased separately) and inside that I place the temperature probe (that comes with the unit). That's it, sit back and know that the Inkbird thermostat is taking care of things.The product itself is well made with sturdy cables, a clearly marked moulded pair of sockets for heating/cooling and an easy to use controller. The cables joining the unit and plug are premoulded and have kink protection. It also has a hook so it can be attached to the wall for easy visibility. The sensor probe can be unplugged from the main unit to allow for cleaning if required.My only criticism and it is a small one is the price, perhaps a little on the expensive side?

This works pretty well. It seems to be very robust and will last quite some time. Setting it is a little tricky as it also has facilities for active cooling as well as heating - so if you are only using it for heating (or cooling) there are menu settings that you need to cycle through that may not be of interest to you unless you've got both heating and cooling systems attached. The booklet is reasonably good, and the temperature probe seems to be pretty accurate. It's nice that the temperature probe can be replaced - which should lengthen the useful life of the device. Very happy with it!

I bought this popular temperature controller for home brewing fermentation, the inkbird comes with a main controller and display unit and an attached socket board to plug in both heating and cooling if required.Setup is so easy and the inkbird takes care of things avoiding overheating or underheating. The temperature sensor on mine seems to be about 2degrees centigrade higher than my normal thermometer, however this is a good thing as i can tape it to the outside of my fermenter and the extra 2 degrees pretty much matches the temp of the wort inside. A brilliant purchase for any home brewer where precise temp control is needed for success.

Works well easy to set up

Great product and good value, used to create a heated proofing cupboard from a old fridge for Pizza Poolish starter.

Our little tortoise goes into her own fridge which is controlled by this, it replaced one that was about 15 years old so they last well, although it is only used for about 5 months a year.Very good if you need one.

Nice piece of kit.
