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.

Introduction of a detector that combines a liquid-type pH/ORP electrode holder and an ultrasonic cleaner!

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.

Dear Sir/Madam, I would like to express my congratulations on the continued prosperity of your company. Thank you very much for your exceptional support. We would like to inform you that our company will be closed for winter holidays during the following period. We apologize for any inconvenience this may cause and kindly ask for your understanding. 1. Winter Holiday Period From Thursday, December 28, 2023, to Thursday, January 4, 2024. 2.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

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 causing any thermal impact to the base material. 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 you require a detailed technical explanation, please contact us.
