PH water quality on-line monitor
Model：ERUN-SZ1-A-B7
PH (electrode method)
This product is a new generation of intelligent water quality tester independently developed by our company. It is characterized by Chinese menu operation, high stability, superior repeatability, multi-function, etc. It can accurately measure the PH value and temperature value in solution. Widely used in environmental protection, sewage treatment, thermal power, breeding, food processing, printing, metallurgy, pharmaceuticals, fermentation, chemical industry, tap water and other solutions in the PH value of the on-line detection.
