Model 330S H2S & Total Sulfur Analyzer
Brand: Envent Engineering LtdThe Model 330S H2S Analyzer utilizes field proven tape based technology that provides a linear and interference-free output of H2S.
An optional Total Sulfur measurement can be added to the analyzer. Certified for Class I, Div 1, Groups C and D (Group B available).
The Envent 330S/331S H2S Analyzer is a uniquely rugged and simple design that utilizes lead acetate based detection which provides a linear and interference-free output of H2S concentration.
This analyzer can measure a wide range of hydrogen sulfide concentrations from parts per billion (ppb) concentrations to parts per million (ppm) concentrations.
With the addition of a dilution sample system, it can read high concentrations in percentage up to 100%. There are other options available such as the sample system for H2S analysis in liquids or the addition of a hydrogen reaction furnace for total sulfur measurements.
Features- Fast Response times using Rapid Response Algorithm (RRA) ~20 seconds to alarm
- No interference from other components in the sample
- Low power consumption <3 Watts
- Extended tape life of 60-90 days
- Measures up to 5 times the calibrated range
- Quick delivery – as quick as 1 to 2 days for standard systems
- Full field service & training available
