[Free Seminar] Corrosion Environment Solutions for Ensuring Reliability and Longevity of Electronic Equipment and Facility Maintenance (Introduction of Corrosion Environment Diagnosis Kit Eco Checker II)

The usage environment of electronic devices varies, and the impact of corrosion caused by various environmental factors tends to increase. The reliability and lifespan of electronic devices heavily depend on the environment in which they are used. Corrosive substances originating from hot springs, volcanoes, waste, and rivers can corrode electronic components, printed circuit board wiring, connector contacts, and switch contacts of electrical equipment, potentially leading to serious issues. This content is recommended for those who want to solve such challenges: • Does the atmosphere of the operating environment lead to failures in electronic devices? • I want to reduce the risk of failure in harsh environments such as hot springs and wastewater treatment plants. • I want to conduct environmental surveys in large factories with fewer personnel and man-hours. • I want to prolong the lifespan of aging infrastructure as much as possible. We will introduce our original corrosion environment diagnostic kit, Eco Checker II, as well as methods for diagnosing corrosion environments.

3 drops and measurement is completed in 3 seconds, and cleanup is easy. We support rapid and accurate pH measurement from research to manufacturing sites.
