FECS44-200

The FIGARO FECS44-200 is a specialized electrochemical sensor engineered for the detection of ammonia (NH3). It boasts high selectivity to ammonia, ensuring accurate readings even in the presence of other gases like H2S. The sensor provides a linear output and features excellent durability to ammonia exposure, along with a stable baseline and a unique leak-proof structure.

With a detection range of 0 to 200 ppm and a maximum overload capacity of 500 ppm, the FECS44-200 is suitable for various monitoring applications. It operates within a temperature range of -30 to 50°C and a humidity range of 15 to 90% RH. The sensor has a typical response time (t90) of 90 seconds and an expected life of over 2 years under normal conditions.

Key features include a typical output signal of 40 ± 12 nA/ppm, repeatability of ±10%, and a resolution of 2 ppm. The sensor requires no bias voltage and exhibits no position sensitivity. Its compact dimensions (ø20.4mm) and through-hole mounting make it adaptable for integration into portable and fixed installation NH3 monitors, NH3 detectors, and ammonia leak detection systems, particularly in refrigeration units.
