Description
Your team faces a critical challenge: keeping workers safe from H2S exposure while managing the rising costs of gas detection programs. The WatchGas SST1E Serviceable H2S Gas Detector solves this problem.
Most detectors force you into expensive replacement cycles. The SST1E is different. With replaceable sensors and batteries, you extend equipment life across years—not months—cutting your cost of operation dramatically. Configure it once via NFC to match your exact safety needs, then let it work.
It delivers what matters most: early warnings that give workers up to 20 extra seconds to evacuate, continuous monitoring of Low, High, STEL, and TWA levels, and a display 54% larger than comparable units so hazards are impossible to miss. The gel-based electrochemical sensor uses 67% less test gas, eliminating bottlenecks in your testing workflow.
Lighter and more compact than industry standards, the SST1E fits seamlessly into your fleet operations—whether you're managing oil and gas sites, contractors, steel plants, or mining operations. Backed by a 3-year instrument warranty and 2-year sensor warranty, it's built to last.
Applications: Oil and gas upstream, Oil and gas downstream, Contractors, Site maintenance, Turn arounds and shutdowns, Boiler rooms, Steel plants, Laboratories, Shipping, Power generation, Mining
Key Features:
- Utilizes a gel-based Electrochemical sensor
- Prevent H2S exposures with earlier sensor warnings – up to 20 extra seconds to evacuate
- Up to 67% less test gas consumed can save you 1000s and reduces worker testing bottlenecks
- Cumulative background exposures awareness for additional insights for worker and potential leak awareness
- Better visibility for quicker decisions – up to 54% larger display than comparable detectors
- STEL & TWA Alarm Readings
- Proactive safety, compliance and management with the optional RTR solution
- Instrument Warranty: 3 years
- Sensor Warranty: 2 year
Unit Includes:
- Detector
- User Manual
- Calibration Cap
- Certificate of Calibration
