Measure R-value of building materials DIRECTLY
...option to rent system with purchase of the necessary sensors - 1 PHFS-09e heat flux sensor ($250) and an outdoor thermocouple ($20)
Rental option only available in the U.S.
FluxTeq R-value measurement System
There has never been a simple and accurate way to directly measure R-value of building materials.....until now.
The FluxTeq R-value Measurement System is a low-cost Arduino based data acquisition system that is designed to accurately and directly collect R-value data of building materials through its heat flux and temperature sensors.
The system comes packaged with a PHFS-09e heat flux sensor and extra temperature sensor to enable collection of heat flux, inside, and outside temperature measurements simultaneously. The device then processes the data and outputs measurements of R-value. The data is collected and saved as an excel file on an SD card.
This user-friendly system is designed to be used completely independent from a computer. Simply press the button data will start being collected immediately.
This approach is standardized in ASTM C1046 and ASTM C1155 and is the only way to directly measure R-value of building materials with in-situ measurements.
- LCD screen for on-device measurement readout of current measurement.
- SD memory card for data logging.
- Micro USB Power Adapter to keep the device charged.
Key System Features
An extra thermocouple allows for outside surface temperature measurements.
R-value Measurement System RoHS
- In-situ measurement of thermal insulation R-value
- Measure Rvalue of walls, attic, windows, etc.
