Stray current measuring instrument

Stray current measuring instrumentModel: DP-CM3

Function and Features

● AC voltage/high-frequency spectrum channel

● Pipe ground potential channel/transverse potential gradient channel/longitudinal potential gradient channel

Measurement of power-off potential and current density

● Real time recording and storage of measurement parameters for each channel under the project number using a USB interface USB flash drive

● Electronic compass+GPS+4G network (server)

The 7-inch touch screen can set the measurement parameters, storage time, and upload time of each channel, and can view the measurement dynamics of each channel parameter, the measurement spectrum record of each channel, GPS signal, WIFI signal, 4G signal, electronic compass direction, battery level, etc

All measurement data, locations, etc. are transmitted in real-time to remote PCs and large screen displays through 4G network (server) remote communication

● The name of the data save file can be changed to facilitate the classification of measurement data

● Set timed shutdown function
