pH calibration method

A high-precision two-channel meter that can measure not only conductivity but also pH simultaneously or individually.

A pH/conductivity meter ideal for a wide range of applications in Metra Toledo. It is not just a conductivity meter; it can also measure pH simultaneously or independently. Measurement initiation and calibration can be easily performed with a single key operation.

• Analytical Equipment and Devices

pH, conductivity, and ion concentration measurement compatible - simultaneous measurement display for 2 channels.

The portable pH/conductivity meter, SevenGo Duo Pro SG78 by Mettler Toledo, supports pH, conductivity, and ion concentration measurements, allowing for simultaneous high-precision measurement and display of two parameters. It is equipped with features compliant with GLP, ensuring thorough information management functions such as log-on and condition setting protection.

• Analytical Equipment and Devices

By adding modules, it can be expanded to a maximum of three channels. You can freely combine pH, ions, conductivity, dissolved oxygen, and ORP.

The tabletop pH meter from the SevenExcellence series by Metrohm is equipped with a large color display, intuitive and easy-to-understand interface, and allows for method execution with a shortcut click, minimizing preparation time for measurements. By connecting the optional auto-sampler InMotion via the PC software LabX, simultaneous automatic measurement of pH and conductivity is possible. Additionally, user management with varying permission levels from operators to administrators is available, enabling analyses to be conducted with consistent settings and parameters by creating methods. These methods can only be modified by the creator, and fingerprint authentication is also possible, ensuring high security management.

• Other physicochemical equipment

Efficient daily operations with an easy-to-use pH meter, SevenCompact.

The tabletop pH meter from the SevenCompact series by Metrohm includes many measurement parameters in the main unit, and we offer numerous options for data input and storage. Calibration and measurement can be easily achieved with just the press of a single key. This series is ideal for meeting the stringent needs and GLP requirements of the pharmaceutical industry and testing laboratories, thanks to its rich data storage and input capabilities.

[Speaker] Tadahiro Maruyama, Director of the Business Creation Division, Chubu Electric Power Co., Inc. (Also Deputy COO of Chuden Telemetering LLC) [Key Lecture Content] Chubu Electric Power is expanding telemetering through a smart meter communication network to gas and water services. In the next phase, we aim to integrate these accumulated data into a multi-infrastructure DX business, merging with energy and water services, and striving for a circular and sustainable community across our entire group. This time, I will explain the actual initiatives related to these efforts. [Lecture Items] 1. Automatic Meter Reading by Chubu Electric Power 2. Current Status of Chubu Electric Power's Telemetry Business 3. Business Transformation through Infrastructure DX in the Electric Power Sector 4. Horizontal Expansion of Infrastructure DX to Water Services 5. Smart City Services through Data Utilization 6. Q&A / Business Card Exchange

[Speaker] Daihei Yamamoto, CEO of F6 Design, Inc. Strategic Consultant / Data Scientist [Lecture Topics] 1. Why is it difficult for "self-driven talent" to emerge from Japanese workplaces? 2. Shifting to a "non-teaching teaching method" - How to change interactions with subordinates 3. Strengthening communication skills through WHI (Why-How-If) 4. Creating an environment that allows for "safe failures" and systems that support self-drive 5. Q&A

To learn more about solar cells, to understand measurement methods, to acquire know-how related to measurements, and to actually try using measuring instruments, we have established a "PV Technical Center" on our headquarters premises, which also serves as a showroom. This center provides support services in the field of measurements for solar power generation, addressing various questions and requests from customers. At the PV Technical Center, we hold PV seminars (free of charge). Please apply through the detailed application URL provided.

In recent years, many people have been facing the challenge of "how to ensure retention and quickly turn new employees into productive members" due to the difficulty in hiring new graduates and the diversification of the environment and values in which young employees have grown. In this seminar, we will introduce some key points of "OJT Leader Development" from the training of the public course "OJT Leader Development Course" scheduled for March next year, based on the know-how cultivated in actual OJT leader training. We will share points that can be immediately practiced in the field, and we look forward to your enthusiastic participation! *Please apply through our company website below. *We have prepared two dates. Please choose a date that is convenient for you. Date: December 17, 2025 (Wednesday) 12:00 PM - 1:00 PM Format: Zoom Webinar Cost: Free Application Deadline: December 15 (Monday) Capacity: 50 people *Registration will close once the capacity is reached. [Content] - Positive role recognition - Understanding the environment and values that have developed - Imagining the "ideal self" as an OJT leader - Skill set for development and more.
