Figaro has introduced TGS6812, a new catalytic hydrogen, methane and LP gas sensor which 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 an adsorbent inside its sensor cap, its cross sensitivity to alcohol is much smaller than traditional catalytic type sensors. In addition, TGS6812 is more durable against silicone compounds than traditional catalytic type sensors.
Please refer to the product information sheets available for each sensor on the Products page for further detail.
