GNST-900Stype
COD, ammonia nitrogen, total phosphorus, total nitrogenMulti parameter water 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. It can detect more than 40 detection items such as COD, ammonia nitrogen, total phosphorus, total nitrogen, heavy metals, etc. 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"
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"
• Basis for determination of total nitrogen《Color changing acid method
How to translate
