H2S in Gas Analyzer – 1200 Series

With more than 20 years of experience developing sulfur analyzers and parts for those instruments, ASI developed the H2S in Gas Analyzer series 1200.
ASI’s series 1200 delivers continuous H2S analysis in gas samples according to the calorimetric method with lead acetate tape, specific for H2S in conformity with the ASTM approved methods.

The process stream is regulated at 10 PSI. Then a precision flow meter regulates the sample flow and is humidified. Next, the sample is introduced to the specific lead acetate sensing tape that provides an output proportional to the concentration of H2S through the photodiode detector and LED light source optical system. This signal is digitized and analyzed by the advanced microprocessor and related software resulting in a linear 4-20ma output. The current reading is displayed in an LCD, as well as analog (4-20mA) and serial (RS485) outputs.
