Propylene Oxide (C3H6O) Detection

Portable & fixed-point C3H6O detectors for healthcare, pharmaceuticals, chemical manufacturing, agriculture, and environmental testing.

About Propylene Oxide Detection

Propylene Oxide is a colorless, volatile liquid with a faintly sweet odor, essential in the production of polyurethane plastics, propylene glycol, and glycol ethers.

It finds extensive use in the automotive and construction industries for its applications in antifreeze and insulation materials. Its high flammability and capacity to cause respiratory and skin irritation call for strict industrial hygiene and real-time gas monitoring.

Common Challenges

  • High flammability increases the risk of fires and explosions.
  • Respiratory and skin irritation require comprehensive protective measures.
  • Accurate and continuous real-time monitoring is essential to ensure safety compliance.

Current Guidelines


  • PEL-TWA: 100 ppm (240 mg/m³)
