This ECT-100A economical plug-n-play controller can be used for sous vide cooking, and other low temperature heating control (<221F or 105C). It offers PID mode and on/off control mode for heating controls. The PID mode is suited for precision temperature control such as sous vide cooking. The on/off control is suited for controlling devices that are not conductive to be switched too frequently such as the compressor of the refrigerator.
This controller uses an electromechanical relay for power output switching. Although this type of relay makes a little click switching sound and is not as long lasting as the solid state relay (SSR), it does not require a heat sink like the SSR does. Using the mechanical relay significantly reduces the size of the controller and its cost. It is perfect for occasional Sous Vide cooker and refrigerator applications.
A digital silicon band gap sensor is used in this controller. The advantage of this digital sensor is its reliability in moist environments than a thermistor sensor. It can be fully immersed in water over extended periods of time without any issues, and perform with more precision and uniform accuracy over an entire specific temperature range. In addition, the cable of the sensor comes with food grade silicone insulation, as compared to PVC jackets used on most sensors on the market. Silicone is safer than PVC for food application, especially when immersed in solutions that contain alcohol. It is because flexible PVC contains plasticizers that can leach out in alcohol. Silicone is also able to withstand higher temperatures.

Note: this controller is only compatible with silicone bandgap sensors. It is not compatible with PT100 RTD sensors.
