Product Introduction

Working principle: UV fluorescence method

The working principle is to use a thermal converter to convert hydrogen sulfide into sulfur dioxide, and use a sulfur dioxide instrument to measure the content of sulfur dioxide, thereby obtaining the content of hydrogen sulfide. The chemical equation is as follows:

2H₂S＋3O₂→2SO₂＋2H₂O
