Description
The WatchGas SST4 Pump Four-Gas Detector is designed for gas monitoring applications where remote sampling and confined-space assessment are required. The detector can display readings for up to four gases simultaneously through its large, clear backlit display, allowing users to monitor gas conditions in both dark confined spaces and bright outdoor environments. The display automatically illuminates during alarm conditions or can be activated on demand.
The SST4 Pump uses an integrated sampling pump and supports sampling through different probes, ball floats and tubing configurations. These accessories are designed for applications ranging from sampling at elevated points to taking samples from liquid tanks. The detector can also be worn as a diffusion device when required. Its bottom hose connection helps reduce tube kinking, while the industrial-strength alligator clip provides secure attachment during use.
A key feature of the SST4 Pump is its NFC connectivity. When paired with the WatchGas SST Application, users can manage devices, perform bump tests and calibration, assign detectors and download event and data logs. The NFC functionality can also support confined-space processes and data management.
The detector uses induction charging instead of conventional charging connectors, helping reduce the risk of damaged cables and charging ports in dirty or harsh industrial environments. A complete charge cycle takes approximately 5–6 hours. The datasheet specifies typical battery life of up to 50 hours with the low-power catalytic LEL sensor, 18 hours with the high-power catalytic LEL sensor and 100 hours with the NDIR LEL sensor, depending on configuration.
The SST4 Pump is particularly suited to confined-space permit-to-work applications. The datasheet states that the device supports up to 33 m sampling and is designed with a 95 dB audible alarm, rugged housing and accessories intended to make sampling faster and easier in demanding environments.
