Q: Good morning, Will this TDS accurately measure the salt level in my salt-chlorinator pool system?
Asked by:  - 6/10/2014 (Submit an answer)
A: Yes it will technically measure the salt level, but it will also measure everything else in the water. Hence, one would not be able to tell the actual salt level measurement in the water.
