SST5 5-gas
NEW! SST5 | 1 to 5-Gas Models | Multi-Gas Detection
This is small. Really small. WatchGas SST5 detectors set a new standard in 5-gas detection. So slim, compact and lightweight you won’t notice you’re wearing it. No harness. No bulk. Just full 5-gas protection that is typically 42% smaller and stays in place while you work, clipped comfortably in the breathing zone where detection matters most. SST5 displays a large, clear display for quick and the widest operating temperature range in its class and lowest cost of ownership.
Available with multiple gas options: H₂S, O₂, LEL, CO, SO₂, HCN, NH₃, Cl₂, ETO, NO₂, NO, Xs

- Ultra comfortable: up to 40% smaller and up to 30% lighter than comparable 5-gas detectors.
- Safer with up to 20 seconds more to evacuate due to faster sensor response
- Reduced test gas consumption via quicker sensor response potentially saves you 1000s
- Hear above the noise – up to 2x louder than comparable 5-gas detectors
- Quicker decisions for safety with the up to 20% larger display than comparable devices
- On and working over multiple shifts: 200-hour runtime
- More uptime with fewer false alarms; stable sensor performance over the widest operating range (60°C to -40°C / +140°F to -40°F)
- Proactive safety, compliance and management with the optional RTR solution
