The TCA-31 Series analyzers measure the specific composition of gases using a heat conductivity method that utilizes the differences in heat conductivity among electrically charged bodies. The analysis and operations units are housed in a single on-site unit, making maintenance and inspection easy. With a high level of consideration given to safety, the TCA-31 Series comes in two types, a heat explosion type and an internal pressure explosion resistant type. The units can be used for H2 gas analysis in a variety of industrial locations, such as nitrogen refining plants, mining facilities, and petrochemical plants, and, as a meter for safe process management, offer a long operating life, accurate display, and safe operation.

Because analysis cell construction is from divergence and diffusion from the main flow inside the detection device, the flow rate and the flow change hardly deviate from theoretical.

Integrated analysis and operations units unit make maintenance and inspection easy.

A digital display allows accurate on-site display readings.

Integration of the analysis and operation instruments allows easy maintenance and inspection.

A digital display allows accurate on-site display readings.

Complete enclosure of such items as the output device cell port, the cell, and the internal piping ensures that they will not be damaged by explosion, thus eliminating secondary explosions due to sample gases.

The units have wide-ranging transmission capabilities (1 km standard).

The series offers four models: the d2G4 pressure explosion resistant TCA-31 and the fid3aG4 internal pressure explosion resistant TCA-31F, which prevents damage from secondary explosions due to sample gases.
