The SS21N8 is a high-sensitivity electrochemical ammonia (NH₃) sensor designed for precise detection within the 0–100 ppm range. It features a linear output of 100 ± 30 nA/ppm and a fast T90 response time under 30 seconds. With low cross-sensitivity to gases like H₂S, H₂, and NO₂, the SS21N8 ensures reliable and accurate measurements. It is suitable for use in applications such as pharmaceuticals, cosmetics, refrigeration systems, and industrial gas detection systems. The sensor offers a typical operating life of over 24 months in air.
