Process Analysers

Diteco supply process analysers to measure the following components in gas streams:

Hydrogen Sulphide (H2S) in Gases and Liquids

The NovaSulf is a process analyser that measure H2S in gas or liquid streams, for both onshore and offshore sectors, using colorimetric techniques. Measurement ranges vary from very low ppb concentrations to % levels of hydrogen sulphide. This technique is specific to H2S without interferences, and comes in a number of configurations:

  • NovaSulf HG400 Seriesmeasures H2S in natural gas, fuel gas, biogas or LPG

Model HG400 Series Process H2S Analyser

  • NovaSulf HL400 Seriesmeasures H2S in crude oil and other hydrocarbon liquids

Model HL400 Series Process H2S Analyser

  • WaterSulfmeasures H2S and sulphides in waste water, including quench towers, waste water treatment plants and stripped sour water

WaterSulf Process H2S Analyser

Total Sulphur in Gases 

All the sulphur compounds in the process stream are converted to H2S in a reduction furnace, and the H2S is then measured with a NovaSulf colorimetric analyser.

  • NovaSulf TG400 Seriesmeasures total sulphur in gases

Model TG400 Series Process Total Sulphur Analyser

  • DualSulf measures both total sulphur and H2S in gases

DualSulf Process Total Sulphur/H2S Analyser


Model ZOA100 – for 0-1 to 0-25% O2 panel mount


Water vapour in the range 0 - 1,000 ppm (other ranges available on request) can be measured with this analyser using an electrolytic cell.
Water vapour is a notoriously difficult measurement to make as it adheres to stainless steel tubing, valves, filters etc. Diteco use chemically treated tubing to reduce the adherence of the water to the tubing. Our technology allows measurement to be made without the need for calibration
