Review on Mi TDS Pen Water Quality Tester by Micha ochowski ᠌

Revainrating 5 out of 5

Wonderful quality, one hundred percent satisfied!

I apologize for the dirty hands and nails. I came from a dacha (construction site) and immediately set about installing a reverse osmosis filter (I was poking around in the pipes, you understand))) I bought a tester to the filter. What indicators I saw: 378 ppm tap water, after the filter 12 ppm and a couple of tables, what for what, and why))) It may come in handy.

Pros
  • Simple, compact. To check the filter norms.
