Hydrogen Sensor - KHS-EVAL-L-LEL  Datasheet

KHS-EVAL-L-LEL-W is similar in functionality to KHS-EVAL-L-LEL except that the KHS-200 hydrogen sensor is connected via 15 cm (6-inch) wires to the printed circuit board. 

KHS-EVAL-L-LEL-W detects hydrogen gas in the range of 0 to 100% LEL (0 to 40,000 PPM or 0 to 4% hydrogen by volume in air).

Sensor detection Principle:  microcatalytic oxidation reaction of hydrogen. 

High selectivity to hydrogen with no cross-sensitivity to methane.

KHS-EVAL-L-LEL-W has an analog voltage output from 0 to 2 V that is proportional to the hydrogen concentration from 0 to 100% LEL.
