The principle of GL-200 multi-parameter water quality analyzer is in line with the method approved by the environmental protection industry. The colorimetric method adopts tube colorimetry, which can quickly determine the concentration of COD, ammonia nitrogen, total phosphorus and total nitrogen in water without pipetting to the cuvette. The built-in micro thermal printer can print the data after the test, and the test data can be exported through the U disk. The equipment carries the patented technology "Glos Water Quality Intelligent Detection System" to make the detection simple and intelligent. The product has built-in applications such as water quality analysis, data query and guided detection mode. It is widely used in scientific research, universities, sewage treatment plants, water environment testing, enterprise sewage self-inspection and other fields.

• Solid state cold light source is adopted, with optical life of 100,000 hours and stable performance.
• Support the determination of four water pollutants including COD, ammonia nitrogen, total phosphorus and total nitrogen.
• 4.3-inch color screen display, guided operation, the user can easily complete the concentration determination. It is equipped with self-developed Glos water quality intelligent detection system to make the detection simpler and more intelligent.
• Built-in thermal printer supports automatic printing and batch printing.
• With support (16 mm) tube colorimetric, digestion without liquid removal.
• Digestion colorimetric integrated design, no need to change to cuvette detection, more efficient.
• ABS material, high strength, corrosion resistant, high temperature resistant shell.
• Measurement data can be exported by inserting a USB stick.
• Standard G7 digestion instrument, only one key to complete the project digestion operation.
• Equipped with customized pipette, it reduces the error of water sampling and is more stable.
• Equipped with factory-prepared reagents and consumables, there is no need to repeatedly pipette and prepare concentrated sulfuric acid, only need to add water samples in the test tube for testing.
