Flammable gas (EX/LEL) is the leading explosion hazard in industrial settings, capable of triggering catastrophic blasts at critical concentrations. The WANDI EDW500, IECEx-certified and capable of measuring 5 gases simultaneously, provides real-time detection to prevent explosions before they occur...

The legal basis for Korea's 5-gas mandatory measurement is Article 619-2 of the Industrial Safety and Health Standards Rules. The 2017 amendment added CO₂ to the 4-gas requirement, and the December 1, 2024 amendment mandates equipment provision, 3-year record retention, and 119 reporting by safety m...

A 5-gas detector measures the 5 gases legally required for confined space work in Korea (O₂, CO, H₂S, CO₂, LEL). The 2017 OSH Act amendment added CO₂, and the 2024 amendment mandates equipment provision and 3-year data retention. WANDI's EDW500 covers all requirements with 5-gas measurement, IECEx+A...

EC (electrochemical), Pellistor (catalytic bead), and PID (photo-ionization) sensors each have distinct operating principles, strengths, and environments where they should or should not be used. Choosing the wrong sensor type can make accurate measurement impossible. This guide covers the right sens...
