iTH-10 iLOG Thermistor and Temperature Data Logger

iTH-10 iLOG Thermistor and Temperature Data Logger

iLog Thermistor Data Logger is low cost, high accuracy, battery powered, stand-alone external thermistor + ambient temperature data logger. The logger records up to 8 mega-byte of data and stores them in non-volatile flash memory for later retrieval. It can record resistance and is best for 10K NTC thermistor. 

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 to science and laboratory applications where precise and accurate measurement is 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...
