Cosmos XA-4000II for Combustible Gas, O2, CO & H2S Personal Gas Detector
The XA-4000II Series offers a range of robust and versatile personal gas detectors. Depending on the chosen model, these detectors are available for two, three, or four gas applications, making them suitable for various monitoring needs. They are particularly well-suited for confined space applications, and with the attachable pump, pre-entry checks into confined spaces can be conducted.
Designed to be compact and lightweight for personal use, these detectors can be customized with additional features such as a gas sampling pump, sampling hose, and probe complete with dust and moisture traps.
The possible combinations of gases that can be detected include:
- Combustible Gas
- Oxygen (O2)
- Carbon Monoxide (CO)
- Hydrogen Sulfide (H2S)
The XA-4000II personal gas detectors provide reliable and comprehensive gas monitoring solutions for various environments, ensuring the safety of individuals in confined spaces and hazardous areas.
