Description
Your team faces a critical choice: continue managing gas detection with bulky, uncomfortable monitors that slow operations and drain resources—or upgrade to a detector engineered for real-world safety demands. The WatchGas SST5 solves the core problem. It's 40% smaller and 25% lighter than comparable 5-gas detectors, meaning your crew stays comfortable during long shifts while maintaining full detection capability across five gases plus your choice of exotic sensors. Faster sensor response gives workers up to 20 seconds more to evacuate in an emergency—a margin that matters when lives are on the line.
Built for harsh conditions, the SST5 operates reliably from -40°F to +140°F, cutting false alarms and maximizing uptime across your fleet. Its 200-hour runtime spans multiple shifts without interruption. A 20% larger display and up to 2x louder alarm ensure hazards are detected and communicated clearly, even in noisy industrial environments.
Management becomes effortless. The WatchGas Device Link App handles calibration, bump tests, and compliance records automatically, eliminating manual paperwork and reducing test gas consumption—potentially saving thousands annually through faster sensor response.
Whether you're in oil and gas, steel production, hazmat response, or manufacturing, the SST5 adapts to your specific gas detection needs with configurable sensor options. It's the detector that keeps your team safer, more comfortable, and more compliant—without compromise.
Applications: Oil & Gas upstream, Steel production Wastewater, Ship building, First responders, Manufacturing, Shipping, Power generation
Key Features:
- O2, CO, H2S, LEL LPC (Low Power Catalytic), & choice of NO, NO2, CL2, NH3, ETO, HCN, or HCN filtered Sensors
- 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
