[Web Seminar] Product Introduction Seminar for pH Meter MAC-1600 with Automatic Calibration Function

Automating the cleaning of electrodes and two-point calibration with JIS standard solution! Enables reliable pH measurement over an extended period.

The MAC-1600 model is a field-installed pH meter that automates the cleaning of electrodes and two-point calibration using JIS standard solutions. It enables reliable pH measurement over long periods while reducing the burden of maintenance tasks. With a two-channel measurement function that controls two detection units with a single converter, it can be used for pH control or monitoring in various plant facilities. Features: - Labor-saving maintenance: Periodic cleaning of electrodes and calibration with standard solutions helps reduce maintenance efforts. - Highly reliable pH measurement: Automatic and high-precision two-point calibration using JIS standard solutions pH 7 and pH 4 or pH 9 allows for stable continuous pH monitoring over long periods. - Supports 2-channel measurement (optional): Simultaneous measurement with two connected detection units (including liquid delivery control) allows for measurements without gaps during calibration and cleaning. - High cleaning effect with lift-up type air jet cleaning. - Appropriate and practical self-diagnosis messages: If calibration failure or electrode damage occurs, a "instrument failure" signal is output collectively. *For more details, please refer to the PDF documentation or feel free to contact us.

We are pleased to announce that Gywood has been recommended as a featured building material in the special project "Recommended Building Materials" at the Housing Business Fair within the comprehensive exhibition for housing, architecture, and real estate [BREX Kansai]. We will be exhibiting in the "Recommended Building Materials and Equipment" zone, where professionals from the field gather to showcase their recommended materials. We invite everyone to stop by and visit us.

Seminar Overview As the labor shortage in manufacturing sites becomes more severe, the labor costs and time losses associated with the "transportation" of products and components, as well as "cleaning" within factories, have become critical management issues that cannot be overlooked. In this webinar, we will introduce the latest use cases of "Autonomous Mobile Robots (AMR)" and "Commercial Cleaning Robots" that achieve productivity improvements in manufacturing environments. We will specifically address questions such as "How are other companies operating these technologies?" and "What kind of cost reduction effects can be expected after implementation?" by providing concrete explanations of actual before-and-after scenarios and operational flows. Factory managers and members of production technology and DX promotion departments who want to advance automation and efficiency on-site are encouraged to participate! Recommended for: - Those who are unsure about where to start with automation, labor reduction, and DX in their factories. - Those who want to alleviate labor shortages on-site and focus resources on core operations to improve productivity. - Those who want to stay updated on the latest trends in the use of transportation robots (AMR) and cleaning robots.
