H2S Sensor

Introduction

♦  The working principle of H₂S Sensor is measuring concentration of gas by using electrochemistry. The probe consists of electrode and electrolyte. The electrolyte is separated by a selective gas-permeable membrane. The gas diffusing in sensor occurs redox reaction on the surface of electrode. Current is generated in the electrode. The value of current is corresponding to the concentration of gas. Sensor converts the signal in electrode into analog signal.

Usage

♦  Connect H₂S Sensor to any port in SenseDisc.

♦  Expose H₂S Sensor electrode in the air with hydrogen sulfide to collect data.

Notes

♦  Hydrogen sulfide is a kind of colorless rotten egg smell poisonous gas. It is suggested to use Kipp gas generator and put on respirator during experiment.

♦  The electrode is gas-permeable membrane electrode. Try not to break the membrane when using the device.

♦  Add small quantity of ferrous sulfide in narrow mouthed flask. Add two drops of dilute sulphuric acid. Small quantity of hydrogen sulfide will be produced.

Typical experiment

♦  Measure H₂S content
