PID Temperature Controller Kit Voltage AC 180 240V Comes with SSR 40DA Solid State Relay, K Type Thermocouple Sensor, and Black Heat Sink

Works well for me, just wiring circuit diagram given with it was little wrong.

Unit came exactly as advertised. It's working perfectly in my mini greenhouse

Menu took a little while to figure out but once set up it works great. I put it on my cigar humidor as the electronics on it died. Temperature is rock solid on 70 degrees. It can be used for heating or cooling.

Although the instructions were clearly no written by someone who was fluent in English, the device itself performed flawlessly and the kit was excellent.

This worked great for turning my analog electric smoker into a now digital electric smoker. I am very happy how it worked after I was done putting it together. If I had one thing to say about the directions, watch you tube videos on how to put everything together. I am very mechanically inclined and was very confused with the instructions that came with it. I thought the price was decent. The temperature was almost perfect. I will be trying it out on a pork shoulder this weekend. Shipment was also very fast.
