WatchGas SST1E Single Sensor Gas Detector

SST1E Exotics. More flexibility, More Gases.

Same trusted foundation as SST1 single gas detectors, the SST1E offers:

• An expanded range of sensors from standard to specialty gases SST1E: H2S, CO, O2, SO2, Cl2, ETO, HCl, HCN, NO, NO2, NH3, Xs
• Quicker hazard awareness via extra-large gas readings, bumper-protected screen and display (up to 54% larger*)
• Cumulative occupational exposure awareness and low-level gas trends, including background levels signalling early stages of a developing leak
• 3-year battery runtime
• Easier to wear – up to 23% lighter and smaller than comparable detectors!
• Other Features:
• Replaceable sensor and battery
• Up to 3-year battery runtime
• Real-time concentration display
• STEL (Short-Term Exposure Limit) tracking
• TWA (Time-Weighted Average) tracking
• Event logging
• NFC communication
• Compatibility with the WatchGas safety ecosystem (dock, app, kiosk, RTR software)

More about the Xs Sensor:

The Xs sensor is capable of monitoring gas concentrations from 0 to 100 ppm, providing precise readings with 0.5 ppm resolution. To help protect workers in the field, the SST1E triggers alarms at 25 ppm and 50 ppm, offering clear warning points before exposure levels become more serious.

Why Use an Xs Sensor Instead of a Specific Gas Sensor?

A conventional single-gas detector is highly selective:

• CO sensor → Carbon monoxide only
• H₂S sensor → Hydrogen sulfide only
• Cl₂ sensor → Chlorine only

The Xs sensor is different because it acts more like a general toxic organic vapor monitor. This can be useful when workers may encounter multiple solvents or organic chemicals and it is impractical to carry a dedicated detector for each compound.
