FECS44-100 Description

Short technical summary and product information.

The FIGARO FECS44-100 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, and demonstrates excellent durability against ammonia exposure. The sensor features a linear output and a stable baseline, making it suitable for various monitoring applications.

 

With a detection range of 0 to 100 ppm, the FECS44-100 is ideal for portable and fixed installation ammonia monitors, general NH3 detectors, and specific applications like ammonia leak detection in refrigeration systems. Its operating temperature range is -30 to 50℃, and it requires a recommended load resistor of 33Ω. The sensor has an expected life of over 2 years under typical conditions.

 

The sensor's design incorporates a unique leak-proof structure. Its physical dimensions are approximately Ø15.4 x 16.5 mm, and it weighs about 4.5g. The cap color is purple. The sensor operates without a bias voltage and exhibits no position sensitivity. Recommended storage temperature is between 0 and 20℃.
