Perfect checking water filter performance
After a month’s use monitoring drinking water, I've found it accurate and consistent. The unit delivered came with batteries and a carrying case included. Also included was a note from the suppliers asking me to get in touch if I noticed any errors - nice touch. Some reviewers have noted continuing varying read outs. I've noticed something similar when used with hot water but didn't find this a problem as it was mostly used with room temp water. In my opinion, it's accurate to within plus/minus 2%. This is based on ongoing readings given on municipal water, distilled water and stored samples. Granted, these aren't 'standard' samples but over time these samples confirmed the unit's accuracy and repeatability, in my opinion. I bought it to use as a quick check on my Brita water filter's performance and this it did admirably.

o mesmo número de resíduos da água da torneira
Usei um medidor e constatei que a água do filtro tem a mesma qualidade da água da torneira, com o mesmo número de resíduos. Tudo foi instalado conforme o manual. O produto me ajudou a ver que fui enganada
