Temperature controller KT3100 is useful good stuf , have LCD display (not LED),probe and can timer . I tested about 30 pieces and have good experience which I will describe reviews with pros and cons, detailed instructions how to set menu for timer and heating cooling .
Price and buy
Temperature controller can buy from Ebay or AliExpress, good price varies around about 15 usd shipping included. Here is link on Ketotek official store
The Chinese AC wall plug thermostat of course has a good price, standard good design.The design is identical to plug-in wattmeters and timers.Probably the biggest difference is the temperature sensor located on the side, when shopping you can choose different sensor lengths of 1m and 3m.
Wide Range of Application: This temperature controlled outlet plug is widely used for greenhouse, reptile, incubator, terrarium, freezer, refrigerator, heater, fridge, homebrew, vivarium, fermentation, heat mat, and other temperature-controlled system. It can also be used as a timer for cycle timing and countdown.
You can use the thermostat to switch devices, for example, a heating pad, a cooling fan, or a heater.
I consider it a negative that the KT3100 works either as a timer or as a temperature controller. You cannot set the activation of the thermostat according to the timer.
Here is pros:
- Good price about 15usd
- The device is reliable and well made
- You can place the temperature sensor on the cable where it is needed
- The display is OK and the controls work well
Here is cons:
- A thermostat with a timer cannot work together in combination
It’s a good piece for the money,you have a thermostat or timer in one device.When buying, pay attention to the correct choice of socket, EU, FR, US, UK, AU are available.Maybe you don’t need to buy KT3100 from Ketotek you can buy OEM outlet thermostat on aliexpress I think they are the same.
