1. Product Overview
The optical structure of the GL-800Q water quality analyzer and the solid-state cold light source at the inlet ensure stable optical performance and accurate detection results of the GL-900. Equipped with the Glos water quality intelligent detection system, it collects data dozens of times per second and uses filtering algorithms to filter out interference, improving data accuracy. The 8-inch IPS ultra large touch screen makes the measurement results intuitive and clear. It can detect more than 40 detection parameters such as COD, ammonia nitrogen, total phosphorus, total nitrogen, heavy metals, etc. The product is equipped with various application programs including water quality analysis, photometric measurement, self built curves, coefficient curves, sample curves, automatic data printing, batch testing, and guided testing modes.

2. Product application
The GL-800Q water quality analyzer can be widely used for water quality testing in research institutes, wastewater engineering, water environment detection, oil and chemical industry, metallurgy and steel, biopharmaceuticals, dairy industry, textile printing and dyeing, electronic machinery, aquaculture, photovoltaics, forestry, papermaking, and other fields.

3. Detection principle
The detection principle of GL-800Q water quality analyzer for routine detection items: COD is determined using a closed catalytic digestion method with a digestion tube, ammonia nitrogen is determined using a nano reagent method, total phosphorus is determined using an ammonium molybdate spectrophotometric method, and total nitrogen is determined using an alkaline persulfate digestion spectrophotometric method. The water quality detection item is selected, and the light source emits a signal through a sensor. The data is processed by an ARM processor to directly calculate the concentration value of the detected sample.
