iTC-80 iLOG Thermocouple and Temperature Data Logger

iTC-80 iLOG Thermocouple and Temperature Data Logger

iLog Thermocouple Data Logger is low-cost, high-accuracy, battery-powered, stand-alone thermocouple + ambient temperature data logger. The logger records up to 8 megabytes of data and stores them in non-volatile flash memory for later retrieval. 

iLog Thermocouple Data Logger measures wide range of temperatures and works with the following thermocouples: E, J, K, N, T, C. 

Its on-board temperature channel provides environment monitoring and Cold-Junction 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 into the computer's USB port, and the software automatically recognizes it and handles the configuration, downloading, graph viewing and more...
