MOT500

Electrochemical | uses the redox reaction of gas at the electrode surface to generate current, The current is proportional to the gas concentration 。 Solid-state electrochemical | Gas molecules undergo redox reactions on the sensor electrode surface, Ions migrate through the solid electrolyte, generating an electrical signal 。 infrared | Gas absorbs infrared light at a specific wavelength, Concentration is calculated by measuring light intensity attenuation 。 Laser | Gas absorbs laser of specific wavelength, Scan absorption lines by tuning laser wavelength, Measure light intensity attenuation, Calculate gas concentration 。 Catalytic | Combustible gas burns on the catalyst surface, causing resistance change 。 Semiconductor | Gas adsorbs on the semiconductor surface and changes its resistance value 。 PID | UV ionizes gas molecules, Detect ion current 。 Thermal conductivity | Compares thermal conductivity of sample and reference gas 。 Zirconia | Oxygen concentration by oxygen partial pressure difference 。 Ultraviolet | Selective ultraviolet absorption or fluorescence of gas molecules, Concentration measurement 。
