PHG9660 industrial PH/ORP meter
9600 series industrial on-line PH/ORP meter is an on-line water quality monitoring and control instrument with microprocessor.
The meter is equipped with different types of pH electrode or ORP electrode, which is widely used in power plants, petrochemical industry, metallurgical electronics, mining, paper industry, biological fermentation engineering, medicine, food and beverage, environmental protection water treatment, aquaculture, modern agricultural planting and other industries.
The pH (acid, alkalinity) value, ORP (REDOX potential) value and temperature value of aqueous solution were continuously monitored and controlled.
