For over a decade, our company has collaborated with major aerospace research institutions, providing them with a large number of high-quality and effective products, and overcoming many challenges in heat flux density testing. The nuclear power industry has extremely strict requirements for sensors, and RdF's temperature sensors have stability, accuracy, and repeatability that far exceed industry standards, making them particularly suitable for the nuclear power industry. Our company has launched the HFM-4 series multi-channel heat flow meter based on the specific situation in China and the requirements of relevant documents for equipment, which is very suitable for research and testing in energy conservation and emission reduction.
