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.

Series 4000 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
