Post-Abatement (Outlet) H2S Monitoring

These systems have been designed for the continuous monitoring of Hydrogen Sulphide (H2S) levels within the Outlet stack after odour control equipment on Waste Water Treatment Works. Standard ranges of instruments are 0—90 ppb, 0—500 ppb or 0—1500 ppb (H2S).

System Specifications

  • System can be configured to operate from either 110V or 240V mains supply.
  • Standard cabinet is supplied IP66 rated in GRP; cabinets with viewing window are also supplied in GRP and rated to IP56.
  • Single analogue 4–20 mA signal proportional to range.
  • Proven sample line length up to 100 metres using specialist tubing.
  • Optional flow failure facility on sample pump (VFC).
  • Optional text messaging of alarm and fault conditions – subject to suitable network coverage.
  • Optional security key lockable cabinet.
  • Hot dip galvanised frameworks for floor or wall mounting.
  • Dilution system option for high levels of gas.
  • Pumped system to counter the issues related with differential pressure systems caused by changes in flow and pressure.
  • Calibrated to H2S and is not cross sensitive to other gases.
  • Standard system to be serviced every 4 months. This may reduce based on site conditions or may increase if our dilution system has been included.
  • Standard instrumentation cabinet 800 x 600 x 300mm.
  • Standard hotbox dimensions 560 x 380 x 180mm.
  • Safety systems installed to meet HSE judgement on ATEX Directive for Zone 1 and Zone 2 gas stream applications.
  • Standard systems can be easily modified for multi gas applications or to meet specific site requirements as necessary.
  • Standard ranges available 0 – 90 ppb; 0 – 500 ppb; 0 – 1500 ppb and 0 – 20 ppm for Hydrogen Sulphide.
