FluxDAQ Ultra-High Resolution Heat Flux Sensor and Thermocouple Measurement System

The FluxDAQ is a signal measurement system that can be used for accurately measuring and recording precise analog voltage signals from FluxTeq's heat flux/thermocouple thermal sensors. With 8 high resolution differential voltage input channels, the FluxDAQ is not only an inexpensive data acquisition system but also one of a few systems on the market that can accurately precisely resolve heat flux sensor and thermocouple output signals.


Each complete PHFS heat flux sensor package includes an integrated thermocouple which requires 2 differential channels total for each sensor that is simultaneously measuring both heat flux and temperature signals. Therefore, the FluxDAQ can handle up to 4 complete PHFS sensors that are measuring both heat flux and temperature.


The necessary software to operate the FluxDAQ for your computer, which includes a real-time graphical user interface, is included with every FluxDAQ data reader purchase free of charge.
