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.

■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.
