Please email for any purchases. Include your shipping address and the number of sensors and types you would like purchase so that we can estimate the shipping and total costs.


Feel free to include any information about your specific application so that we can provide you with the most appropriate heat flux sensor product.


*Response time is for one time constant or 63% sensor output signal to a heat flux step input

** Temperature range may be larger than specified. Further testing is currently being conducted.


Standard sensor orders come with heat flux and thermocouple wire measurement leads of 3 ft in length. If your application requires longer wire leads then we can provide them at a small additional cost per foot.
