Thermal Data Loggers & DAQs both use Analog-to-Digital Conversion (ADC) to record analog signals. So, with the proper transducer, both a Thermal Data Logger & DAQ are capable of measuring different physical quantities.

However, the ability to capture accurate temperature measurements using a thermocouple requires a special design, like Cold Junction Compensation (CJC). Therefore, although a DAQ can potentially be used for temperature measurement, it won’t be able to use a thermocouple like a Thermal Data Logger can.
