Turbiditetsstandarder

Innan test av förlust av transmitterat ljus på grund av spridande partiklar kalibreras utrustningen med turbiditetsstandarder för att säkerställa tillförlitlig prestanda. Primära formazinstandarder kan användas för att mäta och fastställa värden för alla andra standarder. När stabilitet har uppnåtts bekräftar de färdigblandade sekundära lösningarna att mätarna fungerar korrekt för bästa möjliga avläsningsklarhet. Dessa turbiditetsstandarder används rutinmässigt för att verifiera effektiviteten i vattenbehandlingsprocesser.
