El kit son 15 sobres para diluir en 250 mm de agua destilada y conservado en oscuridad podemos usar para calibrar nuestras sondas durante bastante tiempo varios meses de 3 a 6 meses sin problema, luego preparariamos otra tanda de solucion nueva.

Das Pulver ist für mein Messgerät genau das richtige.Ich rühre es mit 250ml Destilliertes Wasser plus 1Tütchen an. Diese Lösung reicht für 4 Wochen. Dann mache ich die Lösung neu. Es klappt super und mein Messgerät funktioniert immer wieder wie neu.

I bought these since I needed to recalibrate my pool controller. It turned out to be completely out of whack, so I tested the solutions against a known good pH meter and it was spot on, like you use the pH 4.00 and it shows you 3.98 That is amazingly good value for your money.
