Standard per torbidità

Standard per torbidità

Prima di testare la perdita di luce trasmessa dovuta a particelle diffondenti, l’apparecchiatura viene calibrata con standard di torbidità per garantire l’affidabilità delle prestazioni. Gli standard primari di formazina possono essere utilizzati per misurare e determinare i valori di tutti gli altri standard. Dopo aver stabilito la stabilità, le soluzioni secondarie pre-miscelate confermano che i misuratori funzionano correttamente, garantendo la massima chiarezza di lettura. Questi standard di torbidità sono utilizzati di routine per verificare l’efficacia nei processi di trattamento delle acque.
