The cabinet-type water quality online system has the characteristics of high stability, superior repeatability, and multi-function. water quality online system can accurately measure solution parameters such as pH, conductivity, dissolved oxygen, turbidity, heavy metal ions, total phosphorus, and ammonia nitrogen.

Routine testing items: COD|Ammonia Nitrogen|Total Phosphorus|Total Nitrogen|Turbidity
Heavy metal detection items: hexavalent chromium|total chromium
Other test items: Permanganate|Chroma|Hardness

(1) Automatic dosing with less reagents
· Time interval (1-9999h arbitrarily adjustable) Maintenance cycle>720h/time;
· Unique reagent formula, strong anti-ion/turbidity/color interference ability;
(2) 7-inch touch LCD screen
· With parameter settings, calibration settings, instrument debugging, other settings, etc.;
· Colorful interface/simple operation/one-key operation;
(3) Automatic detection and automatic cleaning
· It can automatically clean the sampling pipeline, measurement unit, digestion reaction unit, and pipeline of the measurement unit;
(4) Few movable parts
· Modular design/easy to install/easy to maintain;
· Realize automatic protection of system balance damage, once the temperature controller fails, causing temperature out of control, it can automatically cut off the power supply to ensure safety.

The cabinet-type water quality online analyzer is mainly used in the online monitoring of environmental pollution sources in sewage treatment, papermaking, steel, pharmaceutical, petrochemical, electroplating, metallurgy, printing and dyeing industries.
