application area
COD ammonia nitrogen total phosphorus total nitrogen analyzer (water quality analysis)It can be widely used for water quality testing in research institutes, sewage engineering, water environment testing, petrochemicals, metallurgy and steel, biomedicine, food and dairy industry, wool textile printing and dyeing, electronic machinery, aquaculture, photovoltaics, leather, papermaking, and other fields.
Detection Principle
COD ammonia nitrogen total phosphorus total nitrogen analyzer (water quality analysis)The determination of COD adopts the closed catalytic digestion colorimetric method with a digestion tube, the determination of ammonia nitrogen adopts the Nessler's reagent colorimetric method, the determination of total phosphorus adopts the ammonium molybdate spectrophotometric method, and the determination of total nitrogen adopts the alkaline persulfate digestion spectrophotometric method. The water quality detection items are selected, and the imported cold light source emits a 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
•Support the determination of four parameters: COD, ammonia nitrogen, total phosphorus, and total nitrogen.
•Imported solid-state cold light source with stable optical performance, no need for light source preheating, and a light source lifespan of up to 10 years.
•The measuring instrument and digestion instrument adopt a separate design, which does not affect the stability of the light source system and optical sensor.
•Equipped with Glos water quality intelligent detection system and data averaging calculation dozens of times per second.
•Functions such as automatic printing of test results, batch testing, and guided testing mode.
•The digestion colorimetric method is integrated, without the need to replace the colorimetric dish for detection, and the measurement method is simple and efficient.
•4.3-inch high-definition color screen, flat UI design.
•ABS material, high-strength, corrosion-resistant, and high-temperature resistant shell.
•Equipped with pre made reagents, only the water sample for testing needs to be added to the test tube and then digested for testing.
