MD 331-SDS H2S & Total Sulfur Dual Stream Analyzer

Mercaptan sulfide (H2S) and total sulfur level monitoring system with tape-based measurement technology

  1. General Details

    Optionally, total sulfur measurement can also be made. Approvals: Class I, Div 2, Group A, B, C and D. The device can measure H2S from two lines simultaneously and uses band-based measurement technology that provides protection against linear and high frequency noise and signals.


    • Quick feedback thanks to Rapid Response Algorithm (RRA)
    • Instant danger alarm
    • No interaction with other components in the sample
