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.

In a civil engineering site material yard, not only is material storage conducted, but also the frequent movement of trucks and heavy machinery, unloading, and the movement of workers. On unpaved ground, mud and ruts can occur due to rain, which may reduce work efficiency. Hyper CLT mats are civil engineering CLT materials that utilize wood CLT. By laying them in material yards or storage areas, a work space that facilitates the movement of vehicles and heavy machinery can be established while protecting the ground. They can be laid only in necessary locations, and relocation or repurposing in accordance with construction progress is also possible. The 5×10 panel weighs approximately 230 kg, and the 5×20 panel weighs about 460 kg, making them lightweight and easy to install and remove even with small machinery. After use, they can also be utilized as temporary roads, access routes, or heavy machinery work yards. Additionally, they offer unique benefits of wood, such as glare reduction, noise suppression, and CO2 fixation. As a registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A," these wooden mats can also be used for environmental improvement in material yards and innovative public works.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" or "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for metal crack repair without the application of heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even 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 or download the catalog.
