Overview

　　HK-0253 microcoulometric titrator, in line with the requirements of SH/T 0253, SH/T 0254, SH/T 0222, ASTM D3120, ASTM D3246 and other test methods, the instrument adopts the microcoulometric principle, when the sample to be tested burns in the cracking tube After the redox reaction occurs, the carrier gas is brought into the titration cell and reacts with I3- or Ag+. By measuring the amount of electricity consumed during the electrolytic titration process, according to Faraday's law, the total sulfur or total chlorine content of the sample is obtained. The instrument has the characteristics of high sensitivity and good repeatability. The cooling fan is automatically switched on and off, which saves the trouble of waiting for the optical machine after finishing the sample. The product performance is better than that of domestic similar products.

Scope of application: Determination of total sulfur or total chlorine content of samples from scientific research institutions such as petroleum, petrochemical, environmental protection, commodity inspection, schools, etc.

  Instrument configuration: host, temperature control system, stirrer, computer (including workstation), etc.。
