LPV-1 SITE-LOG Voltage and Temperature Data Logger

The SITE-LOG LPV-1 is a 7-channel voltage plus 1-channel temperature, battery powered, stand-alone data logger, with storage up to 8 MB of data in non-volatile flash memory. Input voltage signals can be from sensors, transducers, transmitters or any other common voltage sources. 

Its on-board temperature channel provides environment monitoring and temperature compensation. 

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...
