1、 Principle
Add a quantitative solution to the sample, and in a strongly acidic medium, use silver
As a catalyst, utilizing a unique dilution injection technique to reduce chloride ion concentration, and utilizing a combination of
Masking agent is used to mask high concentration chloride ions, which are then digested under high temperature and pressure using spectrophotometry
Measure the COD concentration value.
2、 Product Features
The new photoelectric quantitative technology is not affected by interference such as high chromaticity, suspended solids, and bubbles, with high reliability and accuracy, and strong anti-interference ability.
High detection accuracy, low measurement limit, and small long-term drift of the instrument.
It has one click self-test function and self diagnostic function.
Adopting a single channel highly integrated valve group, maintenance and cleaning are simple and fast.
24/7 networking function, monitoring instrument operation status anytime, anywhere.
It has alarm function, quality control function, and reverse control function.
It has automatic cleaning and calibration functions.
Capable of whole point measurement, interval measurement, and external control measurement.
Automatically work after power failure and recovery.
Automatic prompt and reset function for faults and missing reagents (samples).
Fault recording function.
L can save historical data for more than 3 years.
Ensure separate discharge of cleaning solution and waste liquid
