Features and Advantages
⚙️ Easy Configuration - NFC
The integrated NFC communication interface allows for various management solutions based on operational requirements: centralized instrument fleet administration, execution of functional verification protocols, calibration scheduling and tracking, user assignment configuration, and extraction of historical data and event logs. NFC technology provides instant data transmission via simple proximity, eliminating cabling constraints and optimizing maintenance procedures.
? Sensor
Equipped with the latest generation of solid polymer electrochemical sensors, these single-gas detectors eliminate conventional liquid electrolyte, thereby removing risks of leaks, evaporation, and thermal degradation. This design ensures: Long-term zero and sensitivity stability over an extended temperature range (-40°C to +60°C), response time T90 < 10 seconds, reduced bulk factor (40% optimized volume), and resistance to vibrations and mechanical shocks.
?️ Display
Featuring the largest LCD display in its category, the SST1 integrates a high-visibility liquid crystal screen optimized for industrial environments. The graphical user interface simultaneously displays: Remaining service life indication in months/days, operational status (compliance icon), alarm and event history, and NFC chip activation. The anti-glare display is resistant to scratches and chemical splashes (IP68 rating).
Key Benefits
✅ Robust
Designed for critical industrial environments, the SST1 features a certified IP68 protection rating, ensuring complete sealing against immersion (1.5m/30min) and particle ingress. The bi-shell polycarbonate architecture and double-wall design provide thermal insulation, preserving the integrity of electronic components. Integrated polycarbonate side screen protectors guard the surface against impacts, abrasion, and chemical splashes.
? Alert
The multi-threshold alarm system allows for personalized configuration of alert levels: low alarm (LOW) for minimum exposure threshold, and high alarm (HIGH) for immediate danger threshold. Threshold programming is done via NFC interface using a smartphone or the SST-Dock control station, enabling quick and traceable configuration. The SST1 features a 95 dB alarm at 30 centimeters, which is the industry standard and necessary in noisy environments.
? Cost-Effective
The extended conservation technology allows for 12 months of storage without performance degradation, with activation upon first use. The operational life guarantee extends to 24 to 36 months of continuous operation, depending on the sensor type and exposure conditions. It forms an all-in-one unit (sensor-electronics-battery), eliminating costs for cell replacement, battery changes, periodic calibration, and corrective maintenance interventions.
The SST1 single-gas detector delivers autonomous operation for 24 to 36 months depending on sensor configuration. The simplified "plug and play" architecture ensures optimal robustness and cost-effectiveness for users requiring reliable protection with intuitive ergonomics. Full autonomous operation: single activation upon power-on, complete 24/7 life cycle for 2-3 years, total elimination of calibration operations, and removal of battery replacements and charging cycles, drastically reducing logistical constraints. Simplified user interface: Intuitive ergonomics minimize training requirements, allowing immediate deployment by any operator. Optimized fleet management: The SST1/SST-Dock coupling enables the fastest functional tests on the market (< 30 seconds), transforming fleet management into an automated process. This solution centralizes performance verification, regulatory traceability, and replacement cycle optimization for simplified and efficient fleet administration.
Configuration Options
