Introduction of features of pH meters for process (industrial) use.
We utilize it for water treatment for sewage, wastewater treatment for public water bodies and factories, and quality control of manufacturing equipment for production online.
We introduce the features of the pH meter for processes (industrial use) from Toa DKK. <Adoption of Glass pH Electrode> pH is continuously measured using the glass electrode method, allowing for constant control or monitoring of pH. <Conversion of Water Quality Meter Measurement Range to Current Signal for Transmission> It has output for measurement value signals (DC 4-20mA) and control/alarm (ON-OFF contacts). <Ruggedness> Determining the material according to the installation location is crucial. The converter uses robust materials, and the detector holder can be selected based on the customer's site requirements. <Composed of More Than Three Models> The system is composed of more than three models, including the converter (display), detector (electrode holder), and auxiliary equipment, with automatic cleaners added in wastewater treatment facilities. It is important to select the most suitable models for each site and enhance the system (see image). Toa DKK offers a diverse lineup including converters (displays), detectors (electrode holders), cleaners, and auxiliary equipment. *For more details, please refer to the PDF document or feel free to contact us.
basic information
■Converter (Display) It is broadly classified into two-wire and four-wire types, as well as field and panel types. ■Detector (Holder) There are immersion type, insertion type, and flow type detectors, with pH electrodes available in integrated KCl replenishing electrodes and chip exchange electrodes. Furthermore, the chip exchange type comes in KCl replenishing and KCl non-replenishing types, with the KCl non-replenishing type often used for wastewater treatment due to its good maintainability. ■Cleaner Ultrasonic cleaners are versatile, while pulse air jet cleaners are effective for wastewater, sewage, and excrement treatment. Chemical cleaners and lift-up jet cleaners are effective against crystalline dirt, among others. ■Auxiliary Equipment Pole stands, mounting brackets, dedicated cables and connector boxes, as well as calibration kits, are added according to the site conditions.

Applications/Examples of results
<Used in many applications and fields> Applications include water treatment for drinking and wastewater, treatment of effluent from public water bodies and factories, and quality control in product manufacturing equipment for production online use. Most factories and facilities have effluent treatment systems, and many pH meters are used from the neutralization process to the discharge of treated water. For production online use, high reliability and performance (accuracy) are required.
