HK-0253 Microcoulometric Titrator

Overview

The HK-0253 Microcoulometric Titrator complies with the requirements of test methods such as SH/T 0253, SH/T 0254, SH/T 0222, ASTM D3120, and ASTM D3246. It is suitable for determining the total sulfur or total chlorine content of samples in scientific research units such as petroleum, petrochemical, environmental protection, commodity inspection, and schools.

Functional Features

1. Higher sensitivity.
2. Better repeatability for low-content samples.
