7-Channel Voltage Data Logger (SiteView Software Included)

Description

Site-Log LFV-2 data logger is an 8-channel, battery powered, stand alone ,10 VDC voltage data logger. It records up to 4 mega bytes of data and stores it in non- volatile flash memory for later retrieval. Input voltage signals can be from sensors, transducers, transmitters or any other common voltage sources.  Its aluminum enclosure makes it excellent in the harshest industrial environment.
Plug & Play USB port and versatile custom equation simplify communications and engineering unit conversion. 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...
