WatchGas SST5 – Five-Gas Detector

The WatchGas SST5 Five-Gas Detector is a compact, lightweight portable gas monitor designed to detect up to five gases simultaneously in demanding industrial environments. It features NFC connectivity, a large backlit display, configurable gas alarms, IP65/68 protection and induction charging. Its compact design allows comfortable wearing in the breathing zone while supporting applications across oil and gas, steel, wastewater, manufacturing and other industries.

Description

The WatchGas SST5 Five-Gas Detector is a portable multi-gas monitoring device designed to provide continuous personal gas detection in industrial and hazardous environments. The detector can display up to five gases simultaneously, with toxic gas readings shown in ppm or mg/m³ and explosive gas readings in %LEL or %VOL. Its large display and automatic backlight help users clearly view readings in dark environments and during alarm conditions.

The SST5 incorporates NFC communication as standard. When paired with the WatchGas Device Link App, users can manage their detector fleet, perform bump tests and calibration, assign devices and download event logs. Alarm settings can also be configured through the device, SST Dock or Device Link App. High, Low, STEL and TWA alarms are supported, allowing the detector to be configured according to the monitoring requirements of the application.

For use in demanding industrial environments, the SST5 features a double-shot housing and IP65/68 protection. Screen protectors help protect the LCD from scratches. The detector also uses induction charging, eliminating conventional charging connectors that can become damaged in dirty or harsh working conditions.

The SST5 is designed around micro and mini sensor technology and supports a range of sensor configurations, including H₂S, CO, O₂, SO₂, Cl₂, ETO, HCN, NH₃, NO, NO₂ and LEL sensors, depending on configuration. The datasheet also specifies LPC and NDIR LEL sensor options.

With dimensions of 107.9 × 62.4 × 26.1 mm and a weight of approximately 188 g, the SST5 is designed to be worn in the breathing zone. Typical battery life is specified as up to 48 hours with the LPC LEL configuration and up to 200 hours with the NDIR LEL configuration, depending on sensor configuration.
