Review on K Type 4-Channel Thermocouple Thermometer Data Logger with SD Card & LED Alarm by Dustin Keller

I received the recorder and should use it the next day. It looks and feels like a quality recorder. I checked the accuracy of the input at room temperature and everything looked fine. (I haven't tested accuracy at other temperatures.) I had trouble adjusting based on the instructions. Apparently the instructions were a translation from another language into English. After a few tries I set it up and it works as expected. It worked fine when I used it. I would recommend this registrar. It worked well and appears to be well built. However, my advice is to get a registrar and work with it before you need it. The operation is quite intuitive, but there are no instructions. It took me some trial and error to get it set up and working the way I wanted it to. For the money this registrar was a good tool for me to solve the problem.
