Works so far
Chasbeaux•July 1, 2017
Seems to work as advertised . I know it will take time to see if it is really working but after a month and 800 gallons I am satisfied.
LOVE It.

LOVE It....perfect install on the Input and Output to monitor your Reverse Osmosis membrane performance. Unit can be easily calibrate by Pressing either In or Out for about 3sec to calibrate either Input or Output...it then goes into CAL mode on display....press either In or Out to goes to calibrate the measured number...pressing In or Out will make the TDS number Up or Down to 352 based on the NaCl calibration solution of 342ppm. When you done...pressing On Off button one time to lock in the calibration...Display will show END and that is all you have to do to calibrate the unit. Very simple.
Has a great auto shut off feature to save on battery life

Has a great auto shut off feature to save on battery life. I have tested it against my other meters and this proves to be very accurate.

Convenient Inline TDS meter

This works as expected. Having a TDS meter in line is much more convenient than the hand held testers. I also like that this particular model uses readily available standard AA type batteries.
