Overview of the Measurement Computing USB-TC DAQ Device
The Measurement Computing USB-TC is an 8-channel thermocouple USB data acquisition (DAQ) device that features programmable independent alarms for each channel and a sample rate of up to 2 samples per second. It can accept any bare wire ended J, K, R, S, T, N, E, or B type thermocouple and has two integrated cold junction compensation (CJC) sensors. Data is sent to your PC via a USB connection and analyzed using the free Measurement Computing DAQ software suite which is available as a free download.
