MULTI-GAS DETECTORS | A COMPREHENSIVE GUIDE
What Are Multi-Gas Detectors?
Multi-gas detectors are portable devices that can detect several gases at once in the air. They play a vital role in keeping workers safe across many industries, including construction and manufacturing.
Key Features
- Detect up to four primary gases: carbon monoxide (CO), hydrogen sulphide (H2S), flammable gases (LEL), and oxygen (O2)
- Can monitor additional gases beyond the primary four
- Some are rechargeable for long-term use
- Others, like the BW Clip4 and BW Flex, are disposable but need regular upkeep
Types of Multi-Gas Detectors
There are two main types:
- Pumped Detectors
- Actively pull air into the device
- Provide faster, more accurate readings
- Work well in areas with low gas levels or poor air flow
- Diffusion Detectors
- Rely on natural gas movement
- Passively measure gas concentrations
- Don’t need a pump to work
Some detectors come in both pumped and diffusion versions, while others are available in only one type.
By using the right multi-gas detector, workers can spot dangerous gases quickly and take action to stay safe. Regular maintenance keeps these vital tools working properly, helping to prevent accidents in hazardous work environments.
