Measurement principle of Yosemite sensing uv cod measuring instrument: The measurement principle is based on ultraviolet absorption method, and all the way passes through a 254nm monochromator, which only allows 254nm ultraviolet light to pass through. The other path passes through a 546nm monochromator, which only allows 546nm visible light to pass through. When these two beams of light pass through the solution in the absorption cell, they are attenuated due to the absorption of organic matter and turbidity. According to the fact that the absorbance of beer-lambert law sample is related to the concentration and turbidity of organic matter, the detector is used to detect the absorbance, and a series of circuits such as conversion, amplification, rectification and calculation are used to output the measured value of organic matter concentration.

Yosemite sensing uv cod detector can realize fast, accurate and economical on-line monitoring of COD. Application fields include drinking water, surface water, industrial process water, sewage treatment and other fields. It can be used to continuously monitor the organic pollution degree of raw water, sewage plant imports, the removal rate of organic matter during treatment, and the organic pollution degree of industrial circulating water.The ultraviolet absorption process of UV COD instrument can be completed in a few seconds, and the data processor has fast data processing speed, plus the washing time of the sample cell, a measurement process can be completed in about 1 minute, which is an incomparable advantage of other COD measurement methods. Secondly, the interference of UV dual-wavelength measurement on water samples can be compensated and deducted from the results, and there is basically no need to pretreat water samples. Regularly adjust the conversion coefficient of samples measured by the national standard potassium dichromate method to realize low-cost online operation. These distinctive features are the prerequisite for realizing online monitoring.

Product characteristics of uv cod analyzer

1.The water sample pretreatment device adopts maintenance-free design, which can ensure that the maintenance period of the pretreatment device exceeds half a year.

2. The measurement process is completed in an instant, and the measurement process and results completely meet the relevant international standards.

3. Imported devices and innovative analysis flow path design ensure high measurement repeatability, which can reach 3% at present.

4. Fully automatic operation, no need for personnel to be on duty, and intelligent functions such as automatic zero adjustment, automatic calibration, automatic measurement, automatic cleaning, automatic maintenance and automatic recovery can be realized.

5. The online monitoring methods are diversified, which can realize manual measurement at any time, automatic timing measurement, automatic periodic measurement and other measurement methods.

6. No chemical reagent is needed, no secondary pollution is generated, and real-time online monitoring of COD is realized.
