Gear-type accelerated material aging oven with internal air circulation, operating according to specified standards.
The test specimens will be suspended in a chamber maintained at the specified temperature for a designated period to accelerate the degradation process. Afterward, the specimens will be visually inspected and their physical properties measured (e.g., tensile testing) to evaluate thermal degradation properties, such as those of plastics or rubber.
The tested items include automotive parts., Televisions and Computers Exposure to heat affects the lifespan of polymers. Therefore, it is necessary to evaluate the thermal degradation properties of each type of material.
Testing to predict tire service life: Heat Aging Tester for Plastics and Rubber.
Supports international standards covering: ผลิตตามมาตรฐาน ISO 188, JIS K 6257, ASTM D573, UL-746B และ IEC 60216-4-1
Technical Highlights: It enables precise, real-time control of airflow velocity and the air exchange rate within the chamber. Temperature is regulated with high accuracy (±1°C), and test history can be viewed via the touchscreen, which also displays air exchange rate graphs for data analysis.
A wide range of options: There is a standard model available. No.102 and the stackable model. No.103 (Stackable Type) To save space in the laboratory.

Accelerated weathering tester : This test chamber features an internal air circulation control system that allows for the setting of air exchange rates (cycles per hour) by selecting between two airflow speeds: low (0.5 ± 0.1 m/s) and high (1.0 ± 0.2 m/s). The unit is equipped with an airflow control system that manages intake from the bottom and exhaust from the top, facilitating turbulent air circulation and ensuring uniform heat distribution.
Yasuda Accelerated Aging Testers come in two models: adjustable air vent in/out.Manual and automatic operation via touch screen
Both modelsThe device will automatically calculate the air exchange rate via the touch screen.
The device is equipped with a room air temperature sensor, which is an important value for calculating the air exchange rate. It transmits the measured temperature for calculating the air exchange rate. Real-time Can control the maximum temperature. 300 Degree Celsius
For the automatic model, if the room temperature changes, the device will automatically adjust the air vents to maintain the air exchange rate, ensuring that the testing conditions are controlled in accordance with the specified standards.
