Have your dealer do it.  There really isn't any point buying a meter for a test thats done 4 or 5 times a year

I started a discussion about TDS meters about 6 months ago and I came to the conclusion that they don't test true TDS ... I also came to the conclusion that replacing the water every 3 to 4 months is the best solution to combatting high TDS.

How do they test for TDS at a pool/spa store? I'm curious how the calculations are derived.
2005 Hot Spring Envoy still going strong. Million-Mile Club....

I want to get in the spa business so I can surf the internet and use Photoshop all day long.

Zep,

These aren't that accurate because they only test ions in the water and not the full load of gunk (ie: dead bacteria cells, human cells, dirt, ...). The meter works by seeing how fast the charge goes from 1 test probe to the other ... the therory is the more ionic stuff in the water the faster it will travel.

Unless we're talking about a lab grade analyzer, I would imagine they all are inaccurate.
