Be careful when buying a PID. I bought two TET612's almost a year ago on ebay when I first started planning my CP (before I had ever heard of Auber). I did some very basic testing (basically to make sure they powered up and worked with the included K Thermocouple. Yesterday I finally fired up my CP for testing, and it turns out that one of the PIDs has some sort of internal short or current leakage when using an RTD, so it's reading almost 20F higher than it should. It still reads correctly with the thermocouple, but I've already installed RTDs at all measurement points. The great thing about Auber is that they have really responded to interest from the homebrewing community and have been very supportive. Since I found Auber, I've bought all the new parts I've needed from them and have been very pleased. Unfortunately, it looks like I'll be placing an order for a new PID...
