I have a brand new All Power Labs (GEK) Process Control Unit board for sale. This PCU is literally the kitchen sink for instrumentation for your gasifier. Includes thermocouple inputs, pressure inputs, FET outputs, analog inputs, servo control, keypad/display, MicroSD, CANbus, RS-232, USB. If you are looking to get data on your gasifier or to try instrumentation, this is your tool. I also have PDF documenation to go along with it. These are no longer available from All Power Labs, and new cost over $1200. I am looking to sell this to fund a new welder, so the first $700 takes it. Thanks for looking!
