Introducing the features of pH meters for process use (industrial applications).

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.

We would like to introduce the ultrasonic cleaning liquid-type detector "UHC-8D" and the water jet cleaning liquid-type detector "JHC-8C." The "UHC-8D" achieves cleaning effects through the cavitation effect generated by efficiently irradiating ultrasonic waves onto the electrode sensing part. The "JHC-8C," on the other hand, intermittently cleans the electrode sensing part using the pressure of water jet injection, preventing dirt adhesion. The control unit's transparent window includes lamps that indicate cleaning in progress and cleaning notifications. 【Features of UHC-8D】 ■ Ultrasonic cleaning liquid-type detector ■ Cleaning effects achieved through cavitation ■ Adopts burst oscillation method (intermittent irradiation) ■ The electrode holder is available in two types: an internal liquid pressurized type for process pressures below 0.1 MPa and an atmospheric pressure sampling type with internal liquid head pressure. *For more details, please refer to the PDF document or feel free to contact us.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without affecting the base material with heat. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
