Overview

COD rapid analyzer (water quality analysis) G20 COD rapid analyzer, based on method HJ/T 399-2007 "Determination of Chemical Oxygen Demand in Water Quality - Rapid Digestion spectrophotometric method", can quickly determine the concentration value of COD in enterprise wastewater. It uses colorimetric method for measurement, cold light source, narrowband interference technology and microcomputer automatic data processing, and directly displays and prints the concentration value of the sample. The device is equipped with a 4.3-inch full-color LCD screen and a guided detection mode, which reduces learning costs and allows users to easily and quickly get started.

Product Details

COD rapid analyzer (water quality analysis)

application area

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

Add a known amount of potassium dichromate solution to the sample, in a strong sulfuric acid medium, using silver sulfate as a catalyst, and after high-temperature digestion, measure the absorbance of COD at a specific light source wavelength. Imported cold light sources emit light source signals to sensors, which are processed by ARM processors to directly provide feedback on sample concentration values, displayed in mg/L.

Product Features

•The determination of ammonia nitrogen follows the national environmental standard HJ/T 399-2007, and the results are accurate and effective.

•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.

•Multiple samples can be tested, and continuous detection mode can be activated to achieve higher detection efficiency.

•Equipped with Glos water quality intelligent detection system and data equalization calculation of tens of times per second.
•Functions such as automatic printing of test results, batch testing, and guided testing mode.
•Equipped with complete consumables and reagents, with low prices and minimal usage.

•4.3 English high-definition color screen, flat UI design.
•ABS material, high-strength, corrosion-resistant, and heat-resistant shell.
•Dissolve the sample without the need to switch to a white detection method, which is simple and efficient.
•Equipped with pre made reagents, only the water sample for testing needs to be added to the test tube and then digested for testing.
