SST5
The WatchGas SST5 is a compact, rugged five-gas detector built for demanding environments. One of the smallest and lightest in its class, it combines advanced gas detection, configurable sensors, NFC connectivity, and induction charging for reliable everyday protection.
- Reliable Protection in Harsh Environments – IP65/68-rated housing built for dust, moisture, heat, and heavy industrial use.
- Reduced Downtime with Induction Charging – Cable-free charging eliminates connector damage and minimizes maintenance.
- Faster Fleet Management – NFC connectivity streamlines calibration, bump testing, and event log management.
- Immediate Hazard Awareness – Powerful 95 dB alarms provide clear alerts in noisy environments.
- Comfortable for All-Day Wear – Compact, lightweight design ensures comfort during long shifts.
Description
The WatchGas SST5 is a high-performance five-gas detector engineered for industrial safety in the harshest working environments. Approximately 40% smaller and 25% lighter than comparable portable diffusion detectors, the SST5 offers exceptional wearability without compromising durability or functionality.
Built with an IP65/68-rated double-shot housing, the SST5 is designed to withstand extreme conditions across industries, including oil and gas, steel production, wastewater, shipping, and emergency response. Its large, high-visibility display provides clear simultaneous readings for up to five gases, while configurable alarms ensure immediate awareness in hazardous situations.
The SST5 features integrated NFC communication for simplified fleet management through the WatchGas Device Link App, allowing users to manage calibration, bump testing, event logs, and compliance records efficiently. Induction charging technology eliminates exposed charging ports, reducing wear and improving long-term reliability in dirty and demanding environments.
