iLog Thermistor Data Logger

Thermistor + Ambient Temperature Data Logger

iLOG 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 4 mega-byte of data and stores them in non-volatile flash memory for later retrieval. It accepts all kinds of thermistors with the resistance value above 2K at 25°C.

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...
