Real-time measurement of 5 types of gases — from oxygen to combustible gases —
with voice alerts and smart integrated monitoring to protect workers when danger strikes.
The SD-G80 precisely measures oxygen and 5 types of hazardous gases in real time within confined spaces. It wirelessly transmits not only concentration data but also on-site temperature and humidity readings — and proactively prevents accidents through immediate voice guidance and remote alarms when danger is detected.
Simultaneously measures Oxygen (O2), Carbon Monoxide (CO), Carbon Dioxide (CO2), Hydrogen Sulfide (H2S), and Combustible Gas (LEL). If even a single gas exceeds the threshold, an immediate alarm is triggered to protect lives.
Instead of a simple siren, intuitive voice alerts such as "Hazardous gas detected" help workers quickly assess the situation and respond appropriately.
In addition to gas concentration levels, real-time temperature and humidity data are collected from the site, enabling comprehensive work environment monitoring.
Via Bluetooth and wireless networks, site data is automatically transmitted in real time to administrator PCs, mobile apps, and large displays, enabling remote monitoring.
No electrical work required — simply attach to steel structures using powerful magnets for instant setup, ideal for work environments that require frequent relocation.
Combine the fixed unit with the portable detector (G-Finder Multi) for seamless coverage from individual work zones to entire spaces without any blind spots.
Monitor real-time site safety status across a variety of devices — office TVs, on-site control room PCs, and administrator smartphones — all simultaneously.
Through data logging and real-time monitoring, a fully compliant safety management system can be established in accordance with the Occupational Safety and Health Act and the Serious Accidents Punishment Act.
Explore real-world installation cases of hazardous gas detectors deployed across confined spaces, tunnels, pipelines, and more.
Real-time monitoring of hazardous gas concentrations helps prevent accidents before they occur.
