This simple design by Envent Engineering Ltd utilizes a lead acetate based sensing system that provides a linear and interference-free output of H2S and Total Sulfur concentration.
Features:
- Fast response times using Rapid Response Algorithms (RRA)
- No interference from other components in the sample
- Low power consumption
- Extended tape life of 60-90 days
- Measures up to 5 times the calibrated range
- Interference-free Lead acetate sensor
- Quick delivery – as fast as 1 to 2 days for standard systems
