Hi Mike, First I do not calculate conductance, I measure it!!! I set up an DMM with an AC current scale. and made it into an mho meter. The AC supply is from a 120 to 12 volt xfmr loaded with back to back 9 volt zeners and a 5 K pot. in series. I adjust the voltage so that a 100k 1% resistor measures 10 uS or micro mhos.
I have a one cubic centimeter cell made out of two 1 cm X 3 cm plates mounted on a 1 cm thick plastic handle so that 1 cm projects from the end of the plastic. The backsides and edges are insulated. Works GREAT!! The anode is curved to a 2" radius and the rod cathode (3/64" brass) is 1 3/4" from the anode, almost on the center of the theoretical circle. The edges on one of my plates have been rolled, another I have insulated them with lacquer. The mounting point for the sheets are on the back side down about 1 or 2 inches from the top.
