PL-V PRECISE-LOG Voltage Data Logger

PL-V PRECISE-LOG Voltage Data Logger

PL-V is an 8-channel, battery powered, standalone voltage data logger. The logger records eight external voltage sources and saves data in 8-MB memory. 

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

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

Simply plug the logger to computer's USB port, and the software automatically recognizes it and handles the configuration, downloading, graph viewing and more…
