Welcome to FES Sensor Technology GmbH - a leading company in hydrogen sensor technology
Our product portfolio includes high-quality hydrogen (H2)-sensors for a safe hydrogen technology
As experts in the field of hydrogen sensor technology with many years of experience, we offer our customers innovative calibrated precision hydrogen (H2) sensors that are insensitive to siloxanes from the ambient air. They show no cross-sensitivity to hydrocarbons such as methane and ethane and can be used at a relative humidity of 0 % to 100 % and under wet vapour conditions. They are stable over the long-term and do not require calibration.
