HM Digital TDS-3 Handheld TDS Meter with Carrying Case

Very good and nice, and 👌 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).

reliable measurement

Accurate reading for Temperature (even room temperature) and TDS for water. Good for professionals dealing with water purity. Very easy to use. No additional expenditure on solutions, batteries or maintenance. Uses replaceable button cells (batteries) which lasts for years (10000 hours life). Does not have much finish in looks but works fine. Good for testing water at home or while travelling. I always doubted my RO Water purifier. I have found that there is no need to have costly AMC (Annual Maintenance Contract) for my Water filter. Whenever the Water purity reading goes above 75 ppm just replace the filters. I loved testing water while travelling, at my relatives and friends places etc.

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 ok...duplicate product but working normal.

Good product

Need to provide initially calibration certificate

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.

Nice little solids tester for my drinking water maker on my sailboat

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
