Hydrogen Sulfide + Total Sulfur Analyzers

Lead Acetate Based Detection

H2S + Total Sulfur Analyzers

Envent offers a simple and rugged H2S Analyzer to suit your field and plant measurement needs. Utilizing a lead acetate tape based detection system, these analyzers provide a linear and interference-free output.

With a properly designed sample conditioning system our lead acetate tape analyzers measure H2S  in natural gas, LPG's, NGL's, liquid (oil or water) and biogas.  A Total Sulfur measurement can also be provided as a standalone analyzer, or in combination with a H2S measurement. 

  • Class I, Division 1 and 2, Groups B, C, D available
  • Standard ranges from 0-5 ppm to 0-100 ppm, higher ranges with dilution available upon request
  • Custom ranges available: less than 5000 ppb and up to 0-30%
  • 1% accuracy, 1% repeatability for applications ranging 1 to 50 ppm.
  • Modbus serial communications
  • Measures up to 5 times the calibrated range
  • Dual isolated 4-20 mA outputs
  • Interference free
