• Rapid detection of gas leakage with high efficient pump inside
• Easy replacement with cartridge type sensor fitting
• Digital flow sensor to maintain regular flow rate
• Detection of combustible, oxygen & toxic gas from low to high concentration owing to various detection principle
• Stable quality and proved detection principle for service life
• Excellent selectivity by adapting detection principle only for oxygen & toxic gas
• Superior performance for detecting gas below TLV
• Easy configuration of monitoring system with RS-485 Modbus (isolated) Serial communication function
