903 H2S Analyzer – hazardous area versione (ATEX)

The 903 H2S Analyzer for hazardous area (ATEX certified) is designed to measure H2S in gaseous streams. The detection system is based on the highly accurate and specific lead acetate tape method.

The 903’s patented analysis algorithm improves repeatability and linearity, while also increasing dynamic range without the need for dilution.

This analyzer will support ranges up to 0-2000 ppm without dilution.
