Konduktivitetsstandarder
Regelbunden användning av ledningsförmågestandarder i fabriker och laboratorier garanterar att instrumenten alltid är korrekt kalibrerade för exakta avläsningar. Genom att placera sonder i lösningen med känd ledningsförmåga kan utrustningens inställningar justeras före testning. Underhåll av utrustningen möjliggör uppskattning av föroreningar och jonnivåer i prover. I enlighet med industriregler produceras lösningarna under strikt kontrollerade förhållanden för fullständig stabilitet och tillförlitlighet.
