The FIGARO FECS43-20 is a specialized electrochemical sensor engineered for the precise detection of Sulfur Dioxide (SO2). It boasts high sensitivity and selectivity to SO2, ensuring accurate measurements within its 0 to 20 ppm detection range. The sensor provides a linear output and a quick response time of less than 25 seconds (t90), making it suitable for real-time monitoring applications.
A key feature of the FECS43-20 is its stable output signal even at high temperatures, coupled with a unique leak-proof structure. These attributes enhance its reliability and longevity, with an expected life time of over 2 years under normal operating conditions. The sensor operates effectively within a temperature range of -30°C to 50°C and a humidity range of 15% to 90% RH.
Applications for the FECS43-20 include portable and fixed installation SO2 monitors and detectors across various industrial safety fields. Its compact dimensions (ø15x4.3 mm) and through-hole mounting compatibility facilitate integration into diverse monitoring systems.
