REX-C100 220V Digital PID Temperature Controller Kit
A part of the review has been auto-translated.
I have just ordered item and will be at least a couple weeks before delivery but I expect product to be as described and in good condition from my previous dealings with Banggood. I was researching the programming and function of pid and found the pids output is not compatible with the ssr's input. There is a fairly easy hack here: http://www.youtube.com/watch?v=2NpcMycHDvk that fixes problem. I just wanted to let everyone know there might be a little soldering involved in getting this package working together.
Easy to configure, easy for installation. Really liked the PID function is automatic tuning. Needed a little calibration thermocouple with reference thermometer (error-leash was just 2 degrees). Little muffle furnace now stands exactly the desired temperature to within 0.5 degrees. I am very pleased with the purchase
