This is a versatile temperature controller for a household to have. It can be used for various applications such as Sous Vide cooking, controlling an electric smoker, making yogurt, dough proofing, controlling the temperature of a table top toaster oven, or converting a fridge to a low temperature incubator for beer fermentation or sourdough storing. 

The controller offers two different control mode: PID mode and on/off mode. The PID control mode is capable of maintaining the temperature within one degree over a long period of time. The on/off mode is similar to a conventional thermostat, but with better precision. It can be used for controlling refrigerator compressor which does not like high frequency cycling.
The controller has a built-in timer that allows the user to program the temperature profile for his or her application. It can also be disabled for simple operations when timer is not needed.

When timer is enabled, user can input a recipe or a temperature profile with up to 6 steps. Totally 8 different recipes can be stored in the nonvolatile memory of the controller.

This controller is equipped with an industrial grade RTD sensor (class A Pt100 sensor). It is more accurate, more reliable, and covers wider temperature range than thermistor sensors that are commonly used in home appliances. Two sensor configurations are offered. 1) Multi-purpose RTD sensor, which has 6 ft long, double jacked three conductor, high temperature cable. It is can be used for either sous vide cooking or for smoker temperature control. 2) RTD sensor for sous vide. This sensor has a 3 ft long thin ribbon cable that is optimized for sous vide cooling. The thin ribbon cable minimizes the gap between the lid and pot resulted in dropping the wired sensor into the pot. This reduces the water evaporation during the long period of sous vide cooking. It also helps saving energy and reducing electric bills. In addition, we offer more than 30 different configurations of Pt100 RTD sensors that cover a broad range of applications. Any of those sensors can be used with this controller if a mini RTD connector is installed on the end of the cable. If you want to use any of those RTD sensors not listed on this page, please contact us.

1) For Bradley Digital Smoker owners, an extra power cord is needed for the smoker generator. You can either purchase an extra power cord by checking the box for "extra 18 AWG power cord" (NEMA 5-15P to C13 Power Cord), which is above "sensor type option" or using a regular computer power cord of your own.

2) for customer outside North America:

  • The "universal" output socket accepts either US power cord or the European CEE 7/7 cord.
  • This controller has US input plug. For international order, user can get a converter from local electronics store to convert the connection.
  • There's an optional travel plug adapter for power input on the top of this product page. Please select it if you need this plug adapter. If you need adapters for power output, please check here.

  • For countries that use 220-240VAC power line, the maximum control power of this controller is 2800 Watts.
