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.

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

Al parecer mide muy bien el TDS (Total de sólidos disueltos) en el agua. Sin embargo me confundí a comprarlo ya que en realidad quería medir la dureza del agua (cuando busqué "dureza agua" en Amazon salieron infinidad de aparatos para medir el TDS). La dureza es otra cosa (cantidad de magnesio y calcio) mientras el TDS son todos los sólidos. Los suavizadores no afectan el TDS, solo la dureza, y compré el aparato para verificar el funcionamiento de mi suavizador.
