"MORITO" for heatstroke and ventilation measures in factories and warehouses.

Visualize a safe and comfortable environment in the workplace or office with temperature, humidity, and CO2 sensors!

In workplace environments such as food factories, warehouses, and refrigeration facilities, the management of "temperature," "humidity," and "ventilation" is directly linked to the health and safety of employees. The temperature and humidity/CO₂ sensors provided by Harmony address the following challenges: - Maintaining quality and hygiene through temperature and humidity management in food factories and warehouses. - Visualizing the WBGT (Wet Bulb Globe Temperature) to assess the risk of heatstroke during the summer in advance. - Monitoring humidity to prevent excessive dryness and the spread of viruses in winter. - Supporting measures against "stale" air and "oxygen deficiency" by visualizing CO₂ levels in homes and offices. - Enabling immediate response to abnormalities with real-time monitoring and notification functions. Utilizing sensors for "visualization" leads to the prevention of health hazards and improvement of the working environment. Why not implement safety measures that can be easily installed and started immediately? *For more details, please download the catalog or contact us.*
