LH580

5-IN-1 PORTABLE GAS DETECTOR

LH-580 5-in-1 Gas Detector is an explosion-proof portable gas detector compliant with IMO MSC.581(110) (Revised Recommendations for Entry into Ship Enclosed Spaces). Certified with CCS Type Approval, CCS Marine Product Certificate and national explosion-proof qualification, it is purpose-built for marine and industrial applications.
It simultaneously detects combustible gas, CO,H₂S, O₂ and CO₂ concentrations. Fitted with a premium infrared sensor, imported pump and brushless motor, it supports Bluetooth data storage (over 10,000 records) and 40m remote gas sampling, delivering stable, safe and efficient long-distance gas monitoring for diverse scenarios.
