Abstract
Inventia se refera la o metoda si un sesizor pentru determinarea pH-ului solutiilor. Metoda conform inventiei consta în recircularea solutiei al carui pH trebuie determinat în proportie de 1 ml solutie la 99 ml solutie de fond, cu un debit de 1,5 l/min, peste doi electrozi identici de hidrogen, din platina-platina, saturati cu hidogen prin electroliza la curent constant de 10 mA timp de 2 h, într-o solutie de halogenura alcalina, electrozii fiind catozi care se gasesc introdusi în compartimentrul mic, în cel mare se gaseste solutia initiala, masurarea unei tensiuni electromotoare care este proportionala cu diferenta de concentratie creata si determinarea pe curba de etalonare a pH-ului solutiei. Senzorul conform inventiei este constituit din doua sfere de sticla ale caror diametre se afla în raportul 1/4, legate între ele cu un tub capilar, sfere în care sînt introdusi doi electrozi si care sînt prevazute ,cu doua stuturi pentru intrarea si iesirea solutiei.
