Additional Equipment Required


The VL-WF-C WiFi Current Data Logger is an 8-channel, battery-powered, standalone and WiFi current data logger. The logger records eight external current sources and saves data in 8MB memory.

Its aluminum enclosure makes it excellent in the harshest industrial environment.

Embedded WIFI module allows remote data monitoring and downloading.

16-bit ADC makes it well suited for science and laboratory applications where precise and accurate measurements are critical.

Siteview software required and sold separately. One license per site can be used on multiple loggers.
