The CONTHOS 3F Ex state-of-the-art thermal conductivity gas-analyzer is an analytical instrument developed for online industrial use.
Some of the outstanding technical features of LFE's 3rd-generation, microprocessor based gas-analyzer are:
● high-temperature TC-detector (TCD), temperature controlled from 50°C to max. 180°C continuous operating temperature.
● high corrosion-resistance of components in contact with medium
● unusually quick response time: typically ≤ 2s
● response highly independent of the gas flow
● unusually high long-term response stability
● intuitive user-interface based on NAMUR1 –recommendations
● automatic self-diagnosis
● optional dynamic interference correction of up to 3 gases
The technical features of the unique CONTHOS 3 gas analyzer open up new areas of application for the thermal-conductivity principle, as well as help to eliminate weak points in present analysis problems.Choosing the TCD-operating-temperature above that of the dew-point of the sample-gas can, in conjunction with external and internal heated gas lines (field housing only), alleviate the need for a sample-gas cooler.

● heated gas lines within analyzer housing (max. 140°C; field housing only)
● TC-detector with flowed reference cell
in the iron and steel industry
in corrosive process gases in the chemical industry
in all of the "classical" applications of the TCD-principle
