Continuing fine tuning on HFE dry cell

Changed tubing to smaller liquid inlet and larger gas out let in an attempt to control direction of liquid flow, my check valve decided not to work, they wouldn’t open, I guess plastic air valves don’t like NAOH.
Anyway, the flow rate didn’t change stayed at 200ml/min, up’ d the Solution from 5tsp/L to 7 in [...]

Its a Dry Cell, meaning its not immersed in the catalyst, has a smaller size, and seems to have eliminated the edge voltage leaking typical with plate cells. It [...]
