Mercaptan Sulfur Content (Potentiometric Titration Method)

Overview

HK-DP-LC200 Mercaptan sulfur content (potention metric titration method) conforms to ASTM D3227. The instrument adopts potentiometric titration method : the hydrogen sulfide-free sample is dissolved in an alcoholic sodium acetate titration solvent and titrated potentiometrically with silver nitrate solution, using as an indicator the potentional between a glass reference electrode and a silver/silver-sulfide indicating electrode. Under these conditions. The mercaptan sulfur is precipapitated as silver mercaptide and the point of the titration is shown by a large change in cell potential.

Features

·        Windows Operating platforms with convenient operation, straight forward dialog between operator and machine.

·        Real-time display of the titration curve can print and store the titration curve, testing results and data directly.

·        We adopts imported titration unit, makes the instruments measuring accuracy is higher and better stability.

·        The instrument can do the following functions automatically.

·        Cleaning setting value add fluid detect end point, filtering false end, And it features continuous titration function.
