Ideal for measuring heat flux sensor signals, this data acquisition system reads the small DC voltage outputs of heat flux sensors and their thermocouples across 8 differential channels. It provides better than 1 µV resolution, a ±2.048 V range, and 24-bit delta-sigma conversion with on-board cold junction compensation. It connects to a PC over USB and records to .csv.

The HFS DAQ is a low-cost data acquisition system that is designed and packaged together to accurately measure the small analog DC voltage signals that are outputted from HFS heat flux sensors and their integrated thermocouples. The HFS DAQ enables precise measurement resolution at a fraction of the cost to other currently available systems.
The simple, user interface allows for easy control of the software features. While the HFS DAQ is connected to a computer using a USB cable interface, the heat flux and temperature sensor measurement signals can be viewed and recorded simultaneously using our free software. Once the measurements are complete, the data is outputted to a file location of your choice in a standard .csv file format for analysis that will be performed later on.
