SENKO Unveils Proprietary SO₂ Sensor – Precision Meets Affordability 

 

We are pleased to announce the successful development of SENKO’s new proprietary SO₂ (Sulfur Dioxide) gas sensor, Model SS2158, marking another step forward in our mission to offer high-performance gas detection solutions with enhanced cost-efficiency. 

By developing this sensor in-house, SENKO can now provide a more competitive pricing structure to our global customers—without compromising on quality or performance. The SS2158 sensor delivers accurate and reliable SO₂ detection down to 0.1 ppm, featuring excellent linearity, fast response (T90 < 30s), and an advanced filter that eliminates cross-sensitivity to H₂S. 

Key Features of SS2158 

• Measurement Range: 0–20 ppm 
• Resolution: < 0.1 ppm (electronics dependent) 
• Response Time (T90): < 30 seconds 
• H₂S Interference Filter: Up to 1,000 ppm·hours 
• Expected Operating Life: > 24 months in air 
• Operating Temperature: -20℃ to +50℃ 

This sensor will be applied not only to our portable detectors such as SGT, SGT-P, and SP-MGTP, but also to our fixed gas detection system, SI-200E. With this comprehensive integration, we aim to cover a wider range of SO₂ monitoring applications, from industrial safety to automotive and environmental monitoring. 

The development of the SS2158 sensor reflects SENKO's commitment to technical innovation and vertical integration, allowing us to respond faster to market needs, offer more tailored solutions, and enhance supply chain stability. 

Stay tuned as SENKO continues to raise the bar in gas detection performance, while ensuring affordability and reliability in every product we deliver.
