Model 331SDS Dual Sensor H2S & Total Sulfur Analyzer
Brand: Envent EngineeringThe Model 331SDS H2S Analyzer utilizes field-proven tape-based technology that provides a linear and interference-free output of H2S on two streams simultaneously.
An optional Total Sulfur measurement can be added to the analyzer as one of the streams, allowing for simultaneous H2S and Total Sulfur measurement on a common stream.
Certified for Class I, Division 2, Groups C and D.
Features- Fast Response times using Rapid Response Algorithm (RRA) 20 seconds to alarm
- No interference from other components in the sample
- Low power consumption less than 3 watts
- Extended tape life of 60 to 90 days
- Measures up to 5 times the calibrated range
- Fast delivery
- Full field service & training available
