TDS 3 Meter
How to take TDS reading.
All TDS reading needs to be taken at least 4-6 days after installation or filter replacement, not earlier. Carbon dust from brand new filters/system “fools” meter. Carbon dust will be completely gone after 4-5 days of regular use.
Collect all 3 water samples (4-8 oz): pure water line , waste water and tap/source water.
If RO system has any mineral or alkaline post filter, water sample for pure water needs to be taken right after membrane (before alkaline, KDF, calcite or mineral stage).
