WatchGas SST5 — Compact Multi-Gas Detector (1–5 Gases)
The WatchGas SST5 is a new addition to the WatchGas range — the smallest in its class multi-gas detector, measuring from 1 to 5 gases simultaneously. Up to 40% smaller and up to 30% lighter than comparable 5-gas detectors, with up to 200 hours of runtime, induction charging and NFC as standard, and the widest operating temperature range in its class.
Key features
- Simultaneous measurement of 1–5 gases: H₂S, O₂, CO, SO₂ (Micro sensors) plus, optionally, Cl₂, ETO, HCN, NH₃, NO, NO₂, Xs (Mini sensors) and combustible gas LEL (catalytic LPC or infrared NDIR).
- Up to 40% smaller and up to 30% lighter than comparable 5-gas detectors — barely noticeable on the chest.
- Up to 20 additional seconds of evacuation time thanks to faster sensor response.
- Up to twice as loud an alarm as comparable 5-gas detectors.
- Up to 20% larger display than comparable-class devices — faster situational reading.
- Runtime up to 200 hours (version with NDIR LEL sensor); the version with a catalytic LPC sensor runs up to 48 hours.
- The widest operating temperature range in its class: from -40°C to +60°C, with stable readings and fewer false alarms.
- Induction (wireless) charging and NFC as standard — fast pairing and data readout.
- Works with the SST Dock docking station, the Compliance Kiosk, the Device Link App and optional RTR reporting software.

Frequently asked questions (FAQ)
How many gases does the SST5 measure simultaneously?
From 1 to 5 — standard oxygen, CO, H₂S, SO₂ and combustible gas (LEL), with the option to add Cl₂, ETO, HCN, NH₃, NO or NO₂ — in a housing smaller and lighter than comparable 5-gas detectors.
How long does it run on a single charge?
Up to 200 hours in the version with an infrared (NDIR) LEL sensor; the version with a catalytic (LPC) sensor runs for up to 48 hours. Induction charging takes 2–3 hours.
How is it charged and configured?
Via induction (wirelessly), with no contacts to clean; NFC allows quick pairing with the app and event readout without opening the housing.
