5 in 1 Water quality testing strips for hot tubs, swimming pools or spas. Easy, accurate and quick detection of pH, Free Chlorine/Bromine, Total Alkalinity, Cyanuric Acid and Total Hardness. 100 count

Very easy to use.

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

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.

Perfect for testing every chemical in the pool

These strips work very quickly and are so easy to read. They do a great job.

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

These give VERY inaccuarate PH readings - cost me a week and lots of chemicals to correct afterwards - AVOID

Muy bueno

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

Parfait

Brilliant

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 tiraSon fáciles de usar para una revisión rápidaContras ❌Se secan antes de usarlas todasResultado poco fiable pasado un mesEnvase no las protege del aire como deberíaEn resumen: al principio cumplen bien, pero si no las usas todas enseguida, se estropean. No es una opción fiable a medio plazo.
