What would you like to know. The Co2 meter puts out 0-5v which the ASM can accept via bnc (probe) cable spliced into the output of the meter. Then just play with the inputs to get it to match the Co2 readings. It’s been great so far. Nice to see how the PH changes as the Co2 raises.Very cool with the CO2 meter integration. Can you tell us more about that?
