WatchGas SST4 Micro Multi-Gas Detector2>
The WatchGas SST4 Micro Multi-Gas Detector is designed to simultaneously detect up to four different gases: Oxygen (O₂), Hydrogen Sulphide (H₂S), Carbon Monoxide (CO), Sulphur Dioxide (SO₂), Hydrogen Cyanide (HCN), and Combustible Gases (LEL). This detector uses the latest solid-state technology to ensure stable and reliable performance in various environments.
The device is compact and ergonomic, making it lightweight and easy to carry. A user-friendly interface includes a clear LCD display showing gas concentrations, battery level, alarm status, and a simple two-button operation. Enhanced safety is provided through continuous monitoring and real-time alerts to ensure worker safety in hazardous environments.
Durability is a crucial feature of the WatchGas SST4 Micro, built to withstand harsh conditions and ensure reliability in critical situations. Its small and light construction makes it ideal for fieldwork without adding bulk. The detector includes audible, visual, and vibrating alarms to immediately alert users to dangerous gas levels. It is also compatible with the WatchGas SST Docking Station for easy bump calibration and configuration.
The detector features electrochemical and catalytic bead sensor types, offering up to 18 hours of battery life. It operates effectively in temperatures ranging from -20°C to +50°C and humidity levels from 15% to 95% RH (non-condensing).
