RSSBuild your own water quality tester
In response to our item about the commercial TDS (total dissolved solids) water testing tool, somebody sent us a link to this homemade meter, which tests for TDS, EC (electrical conductivity), PPM (parts per million).

MAybe it's just me, but it appears that something-- perhaps the 'buzz up' code-- is really breaking the formatting.

Just to clarify;
PPM (parts per million)
Is a unit of measurement not a water quality characteristic (hardness, turbidity, ...) that is measured.
The DIY conductivity meter will also do pH too (that's how lab pH meters work), it looks like a cool project.
