Gases that can be detected with our single-gas detectors
A single-gas detector is designed to continuously monitor one specific gas. These compact and lightweight devices provide real-time alerts to warn workers of potential toxic exposure, oxygen depletion or flammable gas risks. Unlike multi-gas detectors, single-gas detectors are smaller, lighter and easier to wear, making them perfect for daily use. They can be clipped to a belt, attached to a uniform or worn on protective gear, ensuring hands-free gas detection for workers in high-risk environments. Depending on the application, our detectors can measure:
- Hydrogen sulphide (H₂S)
- Oxygen (O₂) depletion or enrichment
- Sulphur dioxide (SO₂)
- Carbon dioxide (CO₂)
- Methyl mercaptan (CH4S)
Our single-gas detectors are designed to detect a wide range of hazardous gases, ensuring maximum safety in various industries. This way, we always offer a fitting solution for your needs.
