Monitor the cathodic protection potential

Power law is a new method for the measurement of cathodic protection potential real. It can effectively eliminate the power measurement caused by the IR drop (soil resistivity) of the error of measurement, to measure the pipeline protection potential.

ZKW282 cathodic protection potential monitor USES a high precision, high speed a/d converter of, large capacity data storage, can be to high-speed analog voltage signal collection, transformation, processing and storage. Combined with the advanced signal measurement and processing technology, can be real-time and accurate monitoring and recording of cathodic protection potential power potential in the process of change, fully reflect the changing process of potential power, are favorable for cathodic protection potential method of measuring power tools. Instrument host also includes the clock circuit, measuring time control; Dot-matrix LCD, menu prompt and, according to the measurement process is controlled by single chip microcomputer.

【 application 】

This instrument is suitable for the storage, underground pipe network and so on cathodic protection potential measurement.
