KHS-EVAL-L-PPM detects hydrogen gas in the range of 0 to 4000 PPM (0 to 10% LEL or 0 to 0.4% hydrogen by volume in air).
Sensor detection Principle: microcatalytic oxidation reaction of hydrogen.
High selectivity to hydrogen, and no cross-sensitivity to methane.
KHS-EVAL-L-PPM has an analog voltage output from 0 to 2 V that is proportional to the hydrogen concentration from 0 to 4000 PPM.
