Nissha Co., Ltd. (hereinafter, "Nissha") is set to exhibit an ozone gas sanitization system at Building Maintenance & Clean Expo 2020, to be held November 11 to 13, 2020, at Tokyo Big Sight.

The ozone gas sanitization system combines an ozone generator and detector, motion sensors, and tablet device for control via a wireless network. The system employs ozone sensors by Nissha FIS, Inc. and wireless technology by Nissha SiMICS, Inc., both Nissha Group companies. Ozone gas is effective for inactivating bacteria and viruses, but is harmful to the human body at high concentrations. The system is designed to carry out wireless monitoring of ozone concentrations and realize safe ozone sanitization for facilities such as hotels, which require sanitization of multiple spaces in a short time.
