Brand：Erun
Name：ORP water quality online monitor
Model：ERUN-SZ1S-A-A2
Parameter: ORP (electrode method)
This product is a new generation of intelligent water quality detector independently developed by our company. It is characterized by Chinese menu operation, high stability, superior repeatability and multi-functionality, etc. It can accurately measure the ORP value in the solution.ORP sensor is a composite electrode which is combined by a glass indicator electrode and a reference electrode.The measurement of ORP is based on the potential difference measured in the solution by the working cell composed of the measuring electrode and the reference electrode, and the linear relationship between the ORP value of the solution to be measured and the potential size of the working cell is utilized to realize the on-line monitoring of ORP. The linear relationship between the ORP value of the solution to be measured and the potential size of the working cell is used to realize the online monitoring of ORP. Widely used in environmental protection, sewage treatment, thermal power, aquaculture, food processing, printing, metallurgy, pharmaceuticals, fermentation, chemical industry, water and other industries, water quality ORP online monitoring.
