Portable multi parameter water quality detector

Product Introduction

GNST-800A is a professional grade outdoor portable water quality detector with an integrated design that enables functions such as digestion, air cooling, and detection in one machine. The built-in large capacity lithium battery can achieve operation without external power supply. 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. The imported ST32 ARM processor 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 instrument is equipped with over 800 water quality testing and discharge standards from various industries, allowing you to quickly determine the discharge limits for various pollutants in wastewater. The 8-inch 2K 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, suspended solids, chromaticity, turbidity, heavy metals, etc. The product is equipped with various applications such as water quality analysis, photometric measurement, coefficient curve, sample curve, etc.
