The SITE-LOG LPTM-1 is a 7-channel, battery powered, stand-alone thermocouple data logger. It records the ambient temperature and the seven external thermocouple probes. Data are stored in non-volatile flash memory for later retrieval. Its aluminum enclosure makes it excellent in the harshest industrial environment.
Its on-board temperature channel provides environment monitoring and Cold-Junction compensation.
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
other functions.
