Greetings
I am looking for a stamp circuit to control a steady pulsating dc
square wave of 20 khz to 25 khz. As current increases. I would like
to monitor and save time and current levels across the same
electrodes that current is expected to increase starting around 3.5
ma. and not to exceed 10 ma before shutting down the output. Also
looking for info for a stamp circuit used to measure and record PH
levels, TDS etc.
This site and all who contribute by sharing their knowledge is an
asset to mankind.
I thank you all T.O.
