COMPAQ DAQ 8 Channel Heat Flux Sensor and Thermocouple DAQ

The COMPAQ DAQ is a miniature version of the FluxDAQ High Resolution Data Acquisition System for ease of portability. It includes all the features of the FluxDAQ but without the LCD screen displaying current readings.


The COMPAQ DAQ can handle up to 4 complete PHFS sensors that are measuring both heat flux and temperature.  The devices are pre-programmed to accept heat flux leads in channels 1, 3, 5, and 7 and the associated T-type thermocouples in 2, 4, 6, and 8.

***Note about Software***

The DAQ software is intended for use on Windows.  While we do have a MAC version, we have limited capabilities for troubleshooting and recommend Windows.


- Heat flux sensor & thermocouple signal measurement and data acquisition

- In-situ measurement of thermal insulation R-value using the PHFS-09 series sensors

- Great for educational use and heat transfer courses 

          - Teach concepts of heat vs. temperature with hands-on experiments.
