Multi parameter water quality analyzer

GNST-900S type
COD ammonia nitrogen total phosphorus total nitrogen suspended solids turbidity chromaticity PH heavy metal full parameter water quality analyzer

Product Introduction
GNST-900S is a new generation of high-performance and highly reliable full parameter water quality analyzer based on the intelligent development concept of the Internet of Things. 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 runs faster and has 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. An 8-inch IPS high-definition color touch screen provides intuitive and clear detection results, capable of detecting COD, ammonia nitrogen, total phosphorus, total nitrogen, suspended solids, turbidity, chromaticity, etc PH、 More than 40 testing items, including heavy metals, are included in the product, which includes various applications such as water quality analysis, photometric measurement, coefficient curve, and sample curve.

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, and has been widely used by users.

Measurement principle
The determination of COD is based on the "HJ/T 399-2007 Water Quality Chemical Oxygen Demand Rapid Digestion Spectrometric Method"
The determination of ammonia nitrogen is based on the "HJ 535-2009 Determination of Ammonia Nitrogen in Water Quality - Nessler's reagent spectrophotometric method"
The determination of total phosphorus is based on "GB 11893-89 Determination of total phosphorus in water quality - Ammonium molybdate spectrophotometric method"
The determination of total nitrogen is based on the alkaline persulfate digestion photometric method
