Electrochemical transmitter
Electrochemical transmitter
Model: ZK8800
Electrochemical transmitter is a data acquisition and storage unit of corrosion monitoring system, and is designed and developed according the advanced technical theories of polarization resistance and weak polarization. It can accurately measure the corrosion current density of the test sample in corrosion medium, and consequently calculate annual corrosion rate.
