The USB‑TC01 is a thermocouple measurement device featuring InstantDAQ technology. Instant DAQ 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 USB‑TC01 to any USB port to use your PC as a display and monitor data in real time. The USB‑TC01 is compatible with J, K, R, S, T, N, E, and B thermocouples.
