Features:
• Uses an optical interferometric sensor with high reliability and backed with an 80-year track record
• Gas analyser with refinements made to the optical interferometric sensor developed when our company was founded
• Sensor with no degradation in sensitivity and excellent long-term stability means replacement is not required for 10 years
• Takes measurements using gas-specific refractive indices, making it capable of measuring a wide range of gases
• Capable of detecting corrosive gases like methylene chloride, NH3 and VCM gases
• Flameproof enclosure (ATEX/IECEx/Japan Ex) that can even be used in H2 environment
• Comprehensive self-diagnostic function, and checks of gas concentrations as well as status using MODBUS communications
• Ideal for preventing explosions and monitoring concentrations of VOCs, and monitoring concentrations of hydrogen gas
Application/s:
• Petroleum Refining
• Petrochemicals
• Hydrogen Production
• Foodstuff e.g. breweries)
• Painting (e.g. automobile)
• Gravure Painting
