17 μ s is the non coating response time, and 300 μ s is the coating response time.
*Only for the heat flow response time, the temperature response time may be delayed due to heat sink. Long term delays may affect measurement accuracy.
**The listed high tolerance temperatures; The wire used for E/H series sensors has a high temperature resistance of 600 ° C, while the rest has a temperature resistance of 200 ° C. The temperature tolerance of HFM-7E/H and HFM-8E/H is different during short-term and continuous use.

As a crucial primary sensitive component of a heat flow meter, the accuracy of its measurement results is crucial for the reliability of the heat flow meter
