Gas sensors
For the measurement of gas in the ambient air, we rely on gas sensors from our premium partner FES Sensor Technology. As an expert in hydrogen sensor technology with many years of experience, FES offers innovative calibrated hydrogen sensors that are insensitive to siloxanes. Typical applications of our hydrogen sensors are areas in which hydrogen is produced, stored, transported and used. FES offers hydrogen sensors for industrial leak detection, fuel cell, laboratory, automotive and many other applications. The gas sensors are characterized by the following properties, among others:
- high robustness and long service life
- absolutely maintenance-free
- high sensitivity and selectivity to hydrogen up to the lower explosive limit (LEL)
- insensitive to typical catalyst poisons such as volatile siloxanes and carbon monoxide
