Triple Inline TDS Meter TRM 1-HM Digital vs Titanium S3 Digital Inline -Auto Aqua

[mwilliams62]

HI Everyone
I am looking to buy a TDS Meter unit and I wanted to know which of the two is the better quality.

Titanium S3 Digital Inline TDS Meter with Three Probe Sensors - Auto Aqua

or

Triple Inline TDS Meter TRM-1 - HM Digital..

I know the Titanium is a little bit higher in price but that sometimes does not mean better quality and vise versa..

Has anyone used either one of these and what is your opinion.

The HM digital DUAL meter system is an add on for Spectrapure RO units. I have been using them for years and only replaced 1 unit.

I have the auto aqua and absolutely love it.
I used to use the HM but you can't calibrate it and over time, it got out of whack.
You can calibrate the AutoAqua.
