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

Full field service & training available

* Product specifications subject to change without notice
to improve reliability, function, design, or otherwise.

Optional Equipment:

SDS Dual Stream The 330SDS Analyzer measures two streams at the same time.
Total Sulfur Total Sulfur furnace converts all sulfur compounds to H2S
which allows the analyzer to measure Total Sulfur.
CO2 Dual-beam IR bench. CO2 concentration is displayed on the
second line of display and can be configured as a 2-20 mA
analog output. CO2 ranges from 0-20% to 0-100%
Stream Switching Allows switching of four (4) input streams or from H2S to
Total Sulfur measurement.
Dilution Allows measurements up to 30% H2S using permeable
membrane dilution.
Liquid Sampling Liquid sample system to measure H2S in Hydrocarbon
liquids or water.
Custom Systems Envent can design custom integrated systems to meet
application requirements.
