Ozone (O3) gas disinfects water more powerfully than chlorine, but that same reactivity makes it dangerous to breathe. This case study covers how WANDI's FIX800 ozone detector was installed at a Busan water treatment facility to continuously monitor the legal exposure limit (TWA 0.1ppm) and protect...

Korean OSH exposure limits set NH₃ at TWA 25 ppm / STEL 35 ppm; 300 ppm is IDLH; 15–28 %vol is explosive. The 2012 Gwangju cold-storage NH₃ explosion killed 2 and injured 10; the 2014 Binggrae plant killed 1. WANDI EDW500 portable 5-gas detector — with ATEX/IECEx dual explosion-proof certification,...

Oxygen below 18% vol is legally defined as "oxygen deficiency" in Korea; below 6% causes immediate death. From 2015–2022, 52 workers died in septic tanks and wastewater facilities (KOSHA). The WANDI FIX800 fixed O₂ detector uses an electrochemical sensor (0–30 %vol) to monitor 24/7 and pairs with th...

CO₂ is colorless and odorless — undetectable by human senses. The 2021 Geumcheon-gu accident in Seoul killed 3 and injured 18. WANDI FIX800 fixed CO₂ detector uses an NDIR sensor for 24/7 monitoring, two-stage alarms, and integration with display boards, ventilation fans, and suppression-system inte...
