The main features of this device include:

• 01 Custom high-temperature tensile fixtures — precisely adapted to the µTS system

To meet the special sample clamping requirements of the customer’s µTS mesoscale testing system, a matching set of high-temperature tensile fixtures was custom-developed. These fixtures were specifically designed considering the µTS system’s interface dimensions, force transmission path, and high-temperature operating conditions, ensuring stable and reliable clamping at working temperatures up to 1300°C, distortion-free mechanical signal transmission, and compliance with the experimental accuracy requirements for high-temperature tensile testing.

• 02 Platinum sheet composite temperature measurement — reducing temperature measurement errors

Conventional thermocouples often suffer from unstable thermal contact between the sensing probe and the sample under high-temperature conditions, leading to discrepancies between sensor readings and actual sample temperatures. This device incorporates a C-shaped platinum sheet welded to the thermocouple sensing tip, forming an integrated structure combining the thermocouple and the platinum sheet.

The platinum sheet plays two key roles: First, platinum has excellent thermal conductivity with minimal heat loss, enabling rapid and accurate transfer of the sample's true temperature to the thermocouple. Second, the platinum sheet wraps around the sample, effectively fixing the sensor position and preventing sensor drift caused by vibration or deformation during heating or mechanical testing — thereby ensuring that the temperature read by the sensor closely matches the actual temperature at the measurement point.

• 03 Gold‑coated chamber — efficient infrared reflection and long‑term stable operation

The chamber of this device is treated with a gold‑coating process. Gold has an extremely high reflectivity in the infrared band, efficiently focusing the infrared radiation emitted by the lamp onto the sample area, reducing energy loss and improving heating efficiency.

In addition, the gold coating has good chemical stability, making it resistant to oxidation or discoloration under long‑term high‑temperature operating conditions. This maintains long‑term stable reflection performance, reduces maintenance frequency, and extends the service life of the device.
