Is there a reason why an aquarium type TDS ( Total Dissolved Solids ) meter couldn't be substituted for a conductivity meter?
Granted, they are no where near as accurate as a conductivity meter. But...They are dirt cheap and they do indicate dissolved solids.
Any help would be appreciated. Thank you.
Hi @Ag8n, Do you know how the aquarium TDS meter works? Maybe it really is just a super cheap conductivity meter?
