Takes temperature measurements from several types of thermocouples in a small, portable form factor.

The Temperature Input Device is a thermocouple measurement device featuring InstantDAQ technology. InstantDAQ technology includes built-in software for viewing and logging data that automatically loads when you plug in the device, so you can instantly take temperature measurements with your PC. You can connect the Temperature Input Device to any USB port to use your PC as a display and monitor data in real time. The device is compatible with J, K, R, S, T, N, E, and B thermocouples.The Temperature Input Device includes the NI-DAQmx driver and configuration utility that simplify configuration and measurements. NI-DAQmx supports NI programming environments as well as Python, ANSI C, C#.NET, and MathWorks MATLAB® software.
