Thanks Intense Coffee but that's what I had before, the CS Victor 86B and I just couldn't get it going well. If I touched it mid roast it should go all haywire and have readings all over the place or nothing at all. The software side was perfectly fine and easy to use. When I got it mind from CS it was not modified in anyway (around 4 years ago), it was just a stock Victor 86B off the shelf in a box without any CS branding. I even ran different software to test it and it worked the same. Maybe Cs has got new ones these days but I doubt very much that they are modified and more likely saying that to just make people stop buying a stock Victor 86B for $50 and using his "free" software which he has to pay to develop. Anyway, getting off topic so I'll stop there! I read a few posts on DMMs and I think cosmic couple said that he suggested picking that software, then finding a compatible DMM is the best way? So what software is out there. I'm looking for basic graphing, temp on display, maybe 2 temps for fun? One air, one bean? with saveable profiles. Mac and Windows compatible too. I won't be able to control fans or heat on my roaster. Also I have a future project (well it's been sitting in my garage for ages! I really need some welding done) to built a roaster to go in my woodfired oven. The DMM would really help with that to gauge air and bean temperatures in the oven so hence my reasoning with 2 probes. Everyone keeps telling me it's inconsistent blah blah but they haven't tried it really, and I'm game for a laugh. I've done 2 roasts with a basic setup before, and one turned out amazing, the other a disaster, but that's because I had to manually rotate the beans with a rod for 16 minutes and I ran out of beer so had to run to the fridge for a refill! hahahahahhahaha. Suggestions?
