A practical comparison for process plants, confined-space entry teams and laboratory environments.
Fixed systems monitor known leak sources continuously and can trigger plant-wide alarms, shutdowns and ventilation. Portable detectors protect the person, travel with the worker, and are essential for confined-space entry and maintenance work.
Most sites need both. Use fixed detection around compressors, storage tanks, sample points and analyser houses. Issue portables to every operator entering a hazardous area, plus an area monitor for temporary work zones.
Match the sensor technology to the hazard: catalytic or infrared for combustibles, electrochemical for toxics like H2S and CO, and PID for volatile organic compounds.
