8-Channel Thermocouple Data Logger

The PRECISE-LOG PL-TW is an 8-channel, battery powered, standalone and WIFI-enabled thermocouple data logger. The logger records eight external thermocouples and saves data in 8-MB memory.

Embedded WIFI module allows remote data monitoring and downloading.
16-bit ADC makes it well suited for science and laboratory applications where precise and accurate measurements are critical. Its aluminum enclosure makes it excellent in the harshest industrial environment. 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.
