Easy to use and Accurate reading

Found this product useful. Although the on/off button got stuck maybe due to heavy press. The TDS readings are shown instantly and is nearly constant. Although temperature takes a little more time to stable (sometimes one minutes).

Worth having it

It's been a year since I purchased this HM Digital TDS-3 meter and using it since then. It is a must have for every household who are conscious about their drinking water TDS level (especially with RO water purifier that has manual TDS Controller). No big issue till now. The only problem is it hangs on me thrice. Pulling out the battery comparment (removing the battery) and reinstalling it resolves the issue. It's fine untill and unless it stop working totally. It's very easy to use. You can check the water temperature as well. Overall it's a reliable meter. Note: Only buy from Prime Seller (Amazon Fulfilled seller) and from the seller, aqua fine, to avoid fake ones.

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
