Seem to be accurate
Seem to be accurate when compared to a digital check. Easy to use. Good value

Good strips
We are using them on daily base for testing the water on our hot tub. They are very similar to the ones we got with the hot tub. Just have a little more testing options. Not bad for the price

Do a good job
These are better than other strips of used though they only measure free chlorine not total chlorine. The ph reading is accurate in that it is the same as the water testing kit I use a couple of times a week. I would buy them again. Prompt delivery.

Ph toont steevast hoger dan meting met tabletten, chloor lujkt juist lager aan te geven. Overige waarden kan ik niet vergelijken. Wel snel

Compré estas tiras de prueba para controlar el agua de mi jacuzzi y piscina, y al principio estaban bien: medían pH, cloro, alcalinidad y dureza sin problemas. Sin embargo, a las pocas semanas noté que ya no leía nada: al abrir el bote, muchas tiras estaban casi secas y apenas cambian de color, así que ya no son útiles. Pros ✅ Miden varios parámetros del agua en una sola tira Son fáciles de usar para una revisión rápida Contras ❌ Se secan antes de usarlas todas Resultado poco fiable pasado un mes Envase no las protege del aire como debería En resumen: al principio cumplen bien, pero si no las usas todas enseguida, se estropean. No es una opción fiable a medio plazo.

No són precisas. Después de usar-las un tiempo y comparta con otras marcas no son nada fiables. No comprar está marca
