25 x 16-in-1 Drinking Water Test Strips - Tap Water Quality Analysis for Total Hardness, Lead, Copper, Nitrate

I've used this before I sent the water for lab testing. Values were similar and this also picked up that we have higher potassium in our drinking water. That accuracy was a pleasant surprise

It works great. I have tested all the water that we use and it shows difference in quality for each one.

Compré este kit para analizar el agua del pozo que utilizo para rellenar la piscina. No es un análisis de laboratorio, claro, pero si se realiza correctamente ofrece resultados orientativos bastante útiles. Gracias a este test descubrí no solo la presencia de nitratos, que no sospechaba, sino también otros problemas importantes como la dureza extrema del agua y la alta concentración de carbonatos, que actúan como efecto tampón e impiden ajustar bien el pH. Estos parámetros me ayudaron a entender por qué el agua de la piscina se descontrolaba con tanta facilidad y me han dado una base clara para prevenir complicaciones futuras. Lo recomiendo totalmente para quienes usan agua de pozo y necesitan tener una idea general pero eficaz de la calidad del agua.

The indicators changed after a couple of seconds, but it gives information about the water.

I bought this 16-in-1 drinking water test kit to get a quick overview of my tap water quality. The kit tests a wide range of parameters, including hardness, chlorine, nitrate, nitrite, pH, alkalinity, and several metals, which is much more comprehensive than basic water test strips. The strips are easy to use: dip one into the water for a few seconds, wait the recommended time, and compare the pads with the printed color chart. In my test (see photo), the colors developed clearly and most pads were easy to compare with the reference chart. Pros: * Tests 16 different water parameters with a single strip. * Clear, well-organized color chart printed on the package. * Individually sealed packaging helps keep the strips dry. * Results are available within a couple of minutes. * Useful for checking tap water, aquarium water, or filtered water. Cons: * Some colors are very close together, so distinguishing between adjacent values can be difficult depending on the lighting. * The strip has many test pads, so it’s important to line them up carefully with the chart to avoid reading the wrong parameter. * Like all color-based test strips, the results are approximate rather than laboratory-grade measurements. Overall, this is a practical kit for routine water checks and gives a good general indication of water quality. If you need highly precise measurements for a specific contaminant, a laboratory analysis is still the better choice, but for everyday monitoring this kit offers good value and is easy to use.

Simple d'utilisation et assez précis , j'ai testé le produit avec une eau de source naturelle car je voulais en avoir le coeur net au niveau de cette eau !!!!! résultat correct , une petite notice en français avec un bilan analytique du résultat aurait été un plus .....mais bon !!! bien mettre la bandelette après le test à coté de l'emballage pour comparer les couleurs facilitera la compréhension !!! il manque juste l'analyse micro organique , mais c'est plus cher !!!! :-) mais ravi quand même .
