HM Digital TDS-3 Handheld TDS Meter with Carrying Case

Good product

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).

Very nice

Very very good product

The product which has been delivered to me is not original. The product displayed here has HM Digital Logo marked on the product itself but the product which I got does not have any label of HM Digital. So I feel it is not genuine product.

Don't buy it. Customer care no is not active....My device do not work properly after 2 months of purchase... I can't find any Ph no on customer care

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.

Very good product

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.

Works fine, very precise

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

Purtroppo non ci sono istruzioni in italiano

C'était pareil fonctionne très bien il fait son boulot j'ai déjà changé les piles même avec une utilisation minimes. On verra bien avec les nouvelles piles
