Teledyne’s Model 402REU Hydrocarbon Analyzer utilizes a flame ionization detector for the continuous measurement of total hydrocarbons at trace levels in process gas streams. The principle of operation is based on measuring the ion current generated when organic compounds are dissociated in a hydrogen flame. Full scale monitoring as low as 0-1 ppm is available.

Teledyne’s Model 4020 utilizes a flame ionization detector (FID) for the continuous trace analysis of total hydrocarbons (THC) under a variety of different process conditions. The principle of operation is based on measuring the ion current generated when organic compounds are dissociated in an intense hydrogen flame.

Teledyne's Model 4030 is a microprocessor based, heated total hydrocarbon gas analyzer designed for high accuracy, sensitivity and stability. This instrument is designed to continuously measure a variety of hydrocarbon concentrations from one point.

Teledyne's Model 4040 is a microprocessor-based, oven heated methane / non-methane gas analyzer designed for high accuracy, sensitivity and stability. The 4040 is designed to measure varieties of hydrocarbon concentrations from a sampling point.

Teledyne's Model 4060 is a microprocessor based instrument ideal for the specific monitoring of trace levels of Benzene in gases such as carbon dioxide, air, and nitrogen. Designed as an on-line analyzer in a 19” rack, the Model 4060 comes with three standard ranges, the most sensitive at 100 ppb full-scale.
