Model 4030

Total Hydrocarbon Analyzer



The Model 4030 uses a field proven FID detector in a heated chamber. The chamber is heated to a high temperature to meet US EPA requirements for VOC emissions monitoring.

4000 Series Overview:

All 4000 series units employ the same basic architecture and electronics; however, each analyzer has additional features:

​4020 Total Hydrocarbon Analyzer

​Uses FID to measure total hydrocarbons in ppm in a sample gas stream

​4030 Total Hydrocarbon Analyzer

​Basic 40​​20 with sample system at a higher temperature for heated applications

Avoids condensation of the sample

​4040 Methane / Non-Methane

​Basic 4020, plus temperature-controlled sampling system with GC column to give accurate readings of both methane and non-methane hydrocarbons in a gas stream

4060 Benzene Analyzer

​Same as 4040, but used to measure ppb levels of benzene instead of methane/non-methane

4080 Total Hydrocarbon Analyzer

​Basic 4020 with sample system including stripper to measure total hydrocarbons in an aqueous sample


  • ​Easy to use software, user programmable ranges

  • GC technology used for complete separation of Methane, Ethylene Oxide, Benzene, Styrene, BTX and many other compounds (application dependent)

  • Automatic fuel shut off system

  • Electronic flame-out guard circuit

  • Adjustable alarm and oven settings
