Description
Technical Field

The second electro-hydraulic rod is then activated to easily adjust the height of the electric heater, increasing the accuracy of performance testing. This device effectively secures electric heaters of different sizes, preventing tilting during testing and ensuring a comprehensive view of the heat field distribution, thus improving testing stability.
