Detection Principle
GL-500 modelGlos system multi parameter water quality analyzerThe detection principle of conventional detection items: COD is determined by closed catalytic digestion colorimetric method using a digestion tube, ammonia nitrogen is determined by Nessler's reagent colorimetric method, total phosphorus is determined by ammonium molybdate spectrophotometric method, and total nitrogen is determined by alkaline persulfate digestion spectrophotometric method. The water quality detection item is selected, and the imported cold light source emits the light source signal to the sensor. The data is processed by a RAM processor and directly fed back to the sample concentration value, which is displayed in mg/L.
Product Features
01. Multi parameter detection: supports the determination of 7 parameters including COD, ammonia nitrogen, total phosphorus, total nitrogen, chromaticity, turbidity, and suspended solids.
02. Accurate detection: Developed according to national testing standards, widely applicable for the detection of production and domestic wastewater.
03. Advantages of light source: Imported cold light source is used, with excellent optical performance and a lifespan of up to 100000 hours.
04. Intelligent operation: The device adopts guided operation, and users can easily complete detection operations according to prompts.
05. Intelligent printing: It can be set to automatically print density results upon completion of detection, or select manual printing mode.
06. Continuous measurement: With multiple samples to be tested, the continuous detection mode can be activated to achieve higher detection efficiency.
07. High cost-effectiveness: Equipped with complete consumables and reagents, low price and minimal usage.
08. Pre made reagents: To provide customers with pre made reagents, simply add the sample to detect the value.
09. Easy to operate: Adopting a dual colorimetric system, it also supports the measurement of colorimetric dishes and tubes, making the operation simple and efficient.
10. Intelligent program: 8-inch IPS full-color touch screen, paired with the UI interaction system developed by Greenkey, easy to operate and time-saving.
