Logging of kiln temperature to a computer?

[bjorn.lindberg]

Hello, have anyone tried this? 

I imagine that you could get yourself a thermocouple and log a stream of temperature readings to a computer. You would get a graph of the kiln temp over time, which is useful for a whole lot of things. I know people are already doing this using pen and paper but I imagine you can do better with a computer. 

Anyway, I found this product, have anyone here had any experience with it?

Let me know what you think.

There's a few of us working on DIY kiln controllers over here. That certainly looks like a pretty easy option for logging temps to a computer.

Thanks, this is the kind of thing I am looking for. I will read the other thread and see what you guys are up to.

Whether you're doing it via a homemade controller or just using a thermocouple & logger how would you calibrate the thermocouple? You cuold compare against another thermocouple but how do you know that is calibrated? The only way I can think of is by watching  cones go down while carefully heating at one of the standard rates (60C or 150C per hour).
