Oxygen (O2) Detectors

We supply fixed and portable Oxygen detectors from leading brands including BW, Crowcon, Dräger, Gas Data, GMI, Green Instruments, Honeywell, ION Science, MSA, RAE Systems, Riken Keiki, Senko, and Uniphos. These detectors provide continuous monitoring, alarms, and compliance with safety regulations across industries such as oil & gas, chemical processing, mining, utilities, and confined space entry.

Ensure safe breathing environments with trusted O₂ monitoring solutions.

  • Oxygen deficiency can lead to dizziness, unconsciousness, and death. It often occurs in confined spaces, tanks, silos, tunnels, and mines.
  • Oxygen enrichment increases the risk of fires and explosions, especially in industries handling flammable gases or chemicals.

Oxygen (O₂) is essential for human life and safe workplace operations. Normal ambient air contains about 20.9% oxygen. Any deviation — either deficiency (below 19.5%) or enrichment (above 23.5%) — poses serious risks.
