Strisce indicatrici pH
Le strisce indicatrici di pH misurano i livelli di fosfato attraverso rapide reazioni colorimetriche. Le opzioni a intervallo stretto, intermedio o universale sono pronte per test quantitativi immediati e presentano diversi intervalli graduati per valutazioni accurate. Dopo aver immerso le strisce indicatrici di pH in soluzioni e campioni, basta confrontare il colore prodotto con le tabelle fornite. I test con carta al tornasole compatta possono essere portati sul campo per test in loco oltre a quelli in laboratorio.
