Kinetico A200 Reverse Osmosis PPM

Testing for parts per million in water treated by a Kinetico A200 reverse osmosis system.
Note:
-Tap water was straight out of the kitchen faucet here in Richmond, TX.
-"Fridge Water" was sourced from my refrigerator which has a basic in-line filter which is basically a just a carbon bed.
-The reverse osmosis is water that came straight out of my Kinetico A200 system.
-Water tester is just some basic Amazon purchased unit, nothing special.
