ZKW280 Stray Current Measurer

Given the irregularity and fast change of stray current, high-precision and high-speed analog-to-digital converter and high-capacity data storage and single chip processor system are used to collect, convert, process and store analog potential signal at a high speed. The main unit of the instrument includes a clock circuit, to control measurement time; a dot-matrix LCD displays menu and data, with the measurement process controlled by single chip processor. Subject to repeated technique arguments and a large number of experimental studies, KW280 stray current measurer has been developed into a high-precision intelligent instrument, with the advantages of easy operation, fast measurement, and easy-to-understand result. Data variation can be observed directly from the LCD, and the data regulation can also be carefully analyzed through what the software displays. The measurer has the function of multi-point continuous measurement.

Application Fields
The instrument is applicable to real-time monitoring for spray current of urban and rural underground transmission pipeline and ships
