The TGS6812-D00 catalytic-type gas sensor can detect levels of hydrogen up to 100%LEL. This sensor features high accuracy, good durability and stability, quick response, and linear output. This sensor can detect not only hydrogen but also methane and LP gas, thus making it an excellent solution for monitoring gas leakage from stationary fuel cell systems which transform combustible gases into hydrogen. As the sensor possesses a proprietary filter material inside its sensor cap, its cross-sensitivity to organic vapors is small. In addition, TGS6812-D00 is durable against silicone compounds in harsh environments.

TGS 3870-F00 is a micro-bead type semiconductor gas sensor for the detection of both methane and carbon monoxide. Using a micro-bead gas sensing structure, both methane and carbon monoxide can be detected with a single sensor element by periodic application of two different heater voltages (high and low). Miniaturization of the gas sensing bead results in a heater power consumption of only 38mW (average).

TGS 3870-F00 has low sensitivity to alcohol vapors (a typical interference gas in the residential environment) and has high durability, making the sensor ideal for consumer market gas alarms.
