Hash's Codmax III**COD analyzer has demonstrated excellent performance in COD monitoring applications for photovoltaic wafer cutting fluids. The instrument is mainly used to monitor the chemical oxygen demand (COD) in the finished liquid and filtrate during the silicon wafer dicing process in real time, and its accuracy is of key significance for evaluating the quality of the finished liquid and the reuse of waste liquid.
In specific applications, the Codmax III analyzer provides effective monitoring of wafer cutting products and filtrates. After pretreatment and dilution, the COD value of the finished solution is maintained at about 2400 mg L, while the COD value of the filtrate is about 3400 mg L. This data demonstrates the high stability and accuracy of Codmax III.
The main advantages of this instrument include:
Measuring principle in accordance with environmental standards: Codmax III is measured using the potassium dichromate method and is fully compliant with the latest environmental standards.
Built-in standard verification and automatic calibration: Calibration and review operations can be automatically completed based on the verification results to ensure the accuracy and reliability of the data.
Multi-stage optical metrology system: Effectively shortens the measurement time and improves the accuracy of ultra-low range measurement.
Hash's unique anti-fouling mode: Significantly extends the maintenance intervals of the injection, metering, and digestion units, especially for high-chlorine environments.
Advanced pre-diagnosis and self-diagnosis systemCodmax III is equipped with a hash Prognosys predictive diagnostic system and a Diagnose self-diagnostic function to provide users with preventive maintenance reminders and reduce the risk of equipment downtime.
Overall, the Codmax III**COD analyzer not only excels in monitoring wafer cutting fluids and their effluents, but also earns customer recognition for its efficient operation and maintenance. Its unique technology and functional design make it an ideal choice for COD monitoring of silicon wafer cutting fluid in photovoltaic enterprises, effectively ensuring the stability and efficiency of the production process.
