Water quality analysis electrode classification brief description
Electrode classification Shanghai Joann Water Technology Co., LTD. - Technical Department
Water quality analysis electrodes are mainly divided into two categories from the working principle:
1, electrochemical water quality electrode
2, optical water quality analysis electrode
The measurement parameters of the above two types of water quality analysis electrodes are as follows:
1, electrochemical water quality electrode
A. pH (pH)
B, ORP (REDOX potential)
C, CON or EC (conductivity) can be converted to TDS (total solid solubility), SAL (universal salinity), RES (resistivity)
D, DO (dissolved oxygen) This kind of dissolved oxygen electrode is usually called the coated method of dissolved oxygen electrode or membrane method of dissolved oxygen electrode
E, FCL (residual chlorine) can be converted into HCLO (hypochlorous acid), CLO2 (chlorine dioxide), membrane electrode and non-membrane electrode (three-electrode method or constant voltage method) two forms
F, DOZ (dissolved ozone), using non-film electrode (three-electrode method or constant voltage method)
G, corrosion rate can measure the approximate corrosion rate of circulating cooling water on metal pipelines
H, various ion electrodes such as ammonia nitrogen, potassium ions, chloride ions, sodium ions, fluoride ions, copper ions, chromium ions, etc
2, optical water quality analysis electrode
A. ODO (Dissolved oxygen by fluorescence method)
B, TURB (Turbidity) According to the different ranges of ultra-low turbidity, low turbidity, high turbidity
C, SS (Total solid suspended matter)
D, MLSS (sludge concentration)
E, transparency can be compared with the Seidler disc method
F, chroma can be compared with platinum cobalt chroma method
G, COD (Chemical oxygen demand) use UV254 ultraviolet fluorescence method to quickly measure COD data, divided into high and low ranges
H, chlorophyll
I. Blue-green algae
J. Nitrate nitrogen
K, nitrite nitrogen
The parameters contained in the above two categories of water quality analysis electrodes are the products that our company can provide to the market at present.
