Designed with versatility in mind, it offers pumped sampling and optional diffusion mode to meet varied safety requirements.

Description

WatchGas SST4 Pumped Multi-Gas Detector

The SST4 Pump is built to withstand harsh conditions, with rugged double-shot molding, IP65/68 certification, and compatibility with environments ranging from -20°C to +60°C. The ergonomic design ensures comfortable use during extended shifts, while its lightweight construction makes it ideal for continuous monitoring.

The detector’s large alphanumeric display ensures clear visibility in all conditions, whether in confined spaces or bright outdoor settings. Intuitive LED indicators provide compliance status at a glance, with green for compliant and red for non-compliant.

Equipped with a powerful pump capable of sampling up to 33 meters, the SST4 Pump is a reliable tool for confined space entries. Its long-lasting battery offers up to 55 hours of runtime with low-power catalytic sensors, ensuring uninterrupted operation during multi-day work cycles. Wireless induction charging eliminates port wear, reducing maintenance needs.

With real-time alerts via audible (95 dB), visual, and vibration alarms, the SST4 Pump enhances worker safety. It features advanced datalogging and near-field communication (NFC) for seamless event recording, compliance tracking, and remote configuration using the WatchGas SST Application.

This device provides advanced protection by detecting gases like Oxygen (O₂), Carbon Monoxide (CO), Hydrogen Sulfide (H₂S), Sulfur Dioxide (SO₂), and Combustible Gases (LEL) with precision. Speak to our sales team for sensor availability out with standard 4 gases.
