GNST-900Stype

CODWater Quality Analyzer

Product Introduction

GNST-900S is a new generation of high-performance and highly reliable multi parameter water quality analyzer based on the development concept of IoT intelligence. After 3 years of research and development, the instrument adopts LED cold light source and optical structure, and is equipped with Genesite intelligent detection system. It can perform more than ten data equalization calculations per second. It uses ST32 ARM processor, which has faster operation speed and stronger stability. Thus, the characteristics of intelligence, high performance, low noise, and strong stability of the water quality analyzer have been achieved by leaps and bounds. The 8-inch IPS high-definition color touch screen makes the detection results intuitive and clear, and can detect COD detection items. The product is equipped with various applications such as water quality analysis, photometric measurement, coefficient curve, sample curve, etc.

Application field

The instrument is widely used in scientific research institutes, sewage treatment, environmental monitoring, petrochemicals, papermaking, pharmaceuticals, printing and dyeing, textiles, leather, brewing, electronics, municipal engineering Universities and other industries have been well received by a large number of usersrecognize.

Measurement principle

The determination of COD is based on the "HJ/T 399-2007 Water Quality Chemical Oxygen Demand Rapid Digestion Spectrometric Method"
