The SITE-LOG LPMB-1 is a 7-channel, battery powered, stand-alone voltage/current DC data logger, with storage up to 4 MB of data in non-volatile flash memory. Input voltage/current signals can be from sensors, transducers, transmitters or any other common voltage/current 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.
