HM DigitalAP-2 AquaPro Water Quality Tester

Stelle damit den Leitwert ein beim Umkehrosmose Wasser.Zur schnellen kontrolle meiner Aquarien,wird viel benutzt und bis jetzt kein problem.

I bought this almolst three years ago but never used it until now, only opened it last week, June, 9, 2023. Impressed initially, briefly, if not a little confused switching between modes. I used it twice spanning only a few minutes and now display won't power down or swicth modes, nor will it give me a reading. Fortunatly, i received a new, much much better one free with a new water dispenser but not happy, it was expensive at £18.48 and I expected much better.

Great to have TDS meter. Thank you Amazon.

素晴らしいとおもいます。

Works well, gives you TDS and temperature reading. The magnetic case they tell you to stick on your refrigerator isn't strong enough to hold on
