Premium pumped multi-gas detector with 33-meter sampling range, IP65/68 rating, 55-hour battery life, wireless charging, and advanced datalogging for confined space and industrial safety applications.
The WatchGas SST4 Pumped Multi-Gas Detector is a high-performance solution engineered for detecting multiple gases in demanding environments including confined spaces, industrial sites, and ship holds. Built to withstand harsh conditions with rugged double-shot molding and IP65/68 certification, this detector operates reliably across temperatures from -20°C to +60°C. The device combines versatility with durability, offering both pumped sampling and optional diffusion mode to meet varied safety requirements across diverse industrial applications.
Equipped with a powerful pump capable of sampling up to 33 meters, the SST4 Pump is an ideal tool for confined space entries and remote monitoring. The detector features a large alphanumeric display with intuitive LED indicators that provide compliance status at a glance—green for compliant and red for non-compliant. Its ergonomic design ensures comfortable use during extended shifts, while the lightweight construction makes it perfect for continuous monitoring operations. The device delivers real-time alerts through multiple channels: audible alarms (95 dB), visual indicators, and vibration alerts for immediate hazard notification.
Advanced technology features include wireless induction charging that eliminates port wear and reduces maintenance needs, with 4-6 hours required for a complete charge. The SST4 Pump offers exceptional battery life of up to 55 hours with low-power catalytic sensors, ensuring uninterrupted operation during multi-day work cycles. With advanced datalogging capabilities and near-field communication (NFC) for seamless event recording, compliance tracking, and remote configuration via the WatchGas SST Application, this detector provides comprehensive protection by detecting Oxygen (O₂), Carbon Monoxide (CO), Hydrogen Sulfide (H₂S), Sulfur Dioxide (SO₂), and Combustible Gases (LEL) with precision.
