Model 2000XTC Transmitter

The Model 2000XTC Transmitter from Teledyne Analytical Instruments resets the standard for thermal conductivity detector based applications within the process control industry.

As an intrinsically safe transmitter, packaged within a rugged, weatherproof housing, the 2000XTC is suitable for use in harsh, hazardous outdoor environments.

Using a novel, solid-state thermal conductivity sensor, this cost-effective transmitter can be configured to detect H2, He, N2, Ar, CO2 or a number of other gases of interest in binary or multi-component sample gas mixtures.
