Crowcon Xgard – Fixed Gas Detector
111,00 €
The Crowcon Xgard series is a comprehensive family of fixed gas detectors engineered to meet diverse industrial and marine gas‑monitoring requirements. Designed for use in hazardous and safe areas, the Xgard range supports three sensor concepts—intrinsically safe, flameproof, and safe‑area—allowing precise selection based on application and certification needs.
Each Xgard type is optimized for specific gas‑detection tasks:
- Type 1 & 2 → Toxic gases & oxygen
- Type 3, 4 & 5 → Flammable gases
- Type 6 → Thermal conductivity measurement (e.g., CO₂, CH₄ mixtures)
- Xsafe → Safe‑area flammable gas detection
The rugged construction, wide sensor compatibility, and global approvals make Xgard one of the most widely used fixed gas detectors in oil & gas, marine, wastewater, chemical plants, and manufacturing facilities.
