Instrument Introduction

The economical sulfate analyzer is designed and developed according to the standard HJ-T342-2007 "Determination of Sulfate in Water Quality - Barium Chromate spectrophotometric method". The detection system uses imported optical components, which have stable and reliable performance. A 5-inch large screen display with a simple and easy to understand interface, allowing users to use it quickly and accurately.

Detection Principle

In acidic solution, barium chromate reacts with sulfate to form barium sulfate precipitate, releasing chromate ions. Under alkaline conditions, chromate ions appear yellow. The absorbance of sulfate is then measured by spectrophotometry at a specific wavelength, and the value of sulfate (mg/L) is directly displayed after calculation by the instrument chip.
