Electrochemical Cell Sensor is designed for detecting different gas concentrations through electrolytic current that forms gas electrolytic. This is an extremely sensitive device to test 1 ppm of CD. It comes with the property of selective sensitivity to gases that make it ideal to be used in the detection of toxic gases. It ensures superior linearity at low concentrations that further ensures it usage in different analytical applications. In addition to this, high immunity to interfering gas is also ensured.
