Amphenol TC1326-AS

The TC-1326 MEMS thermal conductivity sensor is a low-power, extremely robust device particularly suited for hydrogen detection, as hydrogen has the highest thermal conductivity of all known gases. Low concentrations of hydrogen in air can therefore be detected by the increase in thermal conductivity of hydrogen-air mixtures. Although the sensor is optimized for hydrogen and methane response (0 to 100% by volume in air), the TC-1326 can also detect other gases and vapors, provided their thermal conductivity difference from the reference gas (air) is sufficiently large.
