H2S sensor

H2S sensor

The amperometric H2S micro-sensor measures the dissolved H2S partial pressure in the water.

Its micro sized glass tip is membrane covered and only permeable for H2S gas. If it is combined with a pH and temperature sensor, the following parameters can be calculated: total dissolved sulphide amount in the sample and the hydrogen sulphide ion/sulphide ion concentration.
