I've tried searching but haven't found a cheap solution for measuring specific gravity digitally. I have seen people determining their alcohol volume using a CO2 calibrated flow meter but they don't seem too readily available either.
I want something I can submerge in a demijohn or other fermenting vessel along with a thermistor or RTD for temperature so I can estimate alcohol content and see when fermentation has finished.
@MH, you know about process control and such , have you seen anything small and cheap that works around 1.500 and lower?
