Check our new KHS-EVAL hydrogen sensor evaluation boards based on the KHS-200 MEMS micropellistor.
KHS-200 is a MEMS based micropellistor hydrogen sensor, packaged in a standard 3-pin TO18 style package with a metal cap and metal mesh filter. KHS-200 detects hydrogen gas in the range of 0-100% LEL (0-4% H2 by volume).
Sensor Principle: Microcatalytic oxidation reaction of hydrogen. Highly specific and selective to hydrogen, with no cross-sensitivity to methane.
