Q
What is Amperometry CL2 sensor ?
A
Amperometry in chemistry and biochemistry is detection of ions in a solution based on electric current or changes in electric current
Amperometry is an electrochemical technique that measures the change in current resulting from chemical reactions
In Process and Control This is used as a sensor to measure the chlorine in the solution.

Q
How does the Amperometry sensor used?
A
In an amperometric method for the detection of chlorine a fixed voltage applied between two electrodes.
Since, the current flow in amperometric sensor is due to chlorine, hence the amount of current flow is directly proportional of chlorine presented to the sensor.
