[Heatstroke/Ventilation Measures] Temperature and Humidity CO2 Concentration Measurement & Watchman Pro Issues Warnings

ISA Co., Ltd. (abbreviated as ISA, located in Shinjuku, Tokyo, President: Koji Yanagihara) has started recruiting free demonstration monitors for its environmental monitoring system "Miharukun Pro," which enables remote centralized management of WBGT (Wet Bulb Globe Temperature) to reduce the burden of heatstroke measures and strengthen safety management systems in schools and support schools. (※Due to a large number of applications, the recruitment for summer 2026 has been closed.) In the demonstration, the installation locations will be considered based on the operational conditions of various facilities such as classrooms, gymnasiums, schoolyards, and pools. The effects of visualizing environmental data, raising awareness through warning lights and email notifications, and reducing the burden of confirmation for teachers and staff will be confirmed. Through actual operation in school settings, it can contribute to the standardization of heatstroke measures, the acceleration of decision-making, and the efficiency of information sharing, thereby improving safety management systems.

In response to the "Special Heat Stroke Warning Alert" and the "Mandatory Heat Stroke Measures" that began full-scale operation in June 2025, we are reintroducing our IoT heat stroke countermeasure solutions. The target products are the three series: "Meru Maru-kun + Heat Stroke Alert," "Miharukun PRO," and "Momoko and Ayaka." With this system revision, heat stroke measures have changed from "effort obligations" to "obligations" for all businesses employing workers. As measures are required across all industries and sites, including government agencies, educational institutions, welfare facilities, distribution, and construction, ISA supports the creation of a safe and secure environment through existing products that can be operated immediately. ■ Introduction of three heat stroke countermeasure products (1) Meru Maru-kun + Heat Stroke Warning Alert Email Distribution Service (2) Miharukun PRO (WBGT compatible model) (3) Momoko and Ayaka Environmental Monitoring Solution (environmental monitoring, recording, alerts) ◆ Main industries and achievements of implementation Local governments (offices, evacuation centers, nurseries) Educational institutions (playgrounds, gymnasiums, classrooms) Medical and welfare facilities (nursing homes, disability support facilities) Distribution and construction industries (warehouses, job sites, delivery hubs) General companies (reception areas, warehouses, employee break rooms)

Utilizing the "Ultra-Low Temperature Freezer Monitoring Solution," a system that automatically monitors temperature and power abnormalities in freezers for storing COVID-19 vaccines, the Miura City Hall is implementing measures to prevent vaccine disposal. This initiative, which involves the introduction of a system that monitors both temperature and power, is one of the few of its kind in the country. <Purpose of Implementation> To monitor temperature and power abnormalities in freezers and ultra-low temperature freezers (deep freezers) storing COVID-19 vaccines, in order to prevent vaccine disposal accidents caused by power outages, equipment malfunctions, and human errors. <Results of Implementation> The system operated during power outages, allowing vaccines to be stored without compromising quality. Additionally, the vaccine storage environment (internal temperature and power abnormalities) can now be checked from smartphones and PCs, leading to reduced work hours for staff and improved operational efficiency. <Freezers monitored by the system at Miura City Hall> - One unit from Japan Freezer Co., Ltd. - One unit from PHC Corporation *For details about the system, please refer to the product PDF. *For more information, visit our company website or the Ipros introduction page. <Note 1> With a 270W freezer, the standard configuration provides 2 hours and 45 minutes of backup. In the maximum configuration (with two additional battery units), it can provide 5 hours and 5 minutes of backup.
