Only different. I need an eight channel digital display that has at least 8 inputs. I need to run it off of ~12v. It has to accept k-type thermocouples, as that it's intended use. I have one like this already: http://www.doric-vas.com/500.htm But it is only available to 6 channels and is powered by 115/230. I'd also like it to cost less than $500. I can't seem to find what I am looking for. Thanks in advance.
