Product Introduction
This instrument is suitable for testing polyethylene pipes, pipe fittings and raw materials. After tableting the raw materials, cut out a cylinder with a diameter slightly smaller than the sample dish, and then use a sharp knife to cut a 15±0.5mg disk-shaped test piece from the cylinder. The time and temperature relationship curve of the sample was analyzed under the specified temperature and air flow, and the thermal stability of the sample was judged by the oxidation induction period.

Main Feature
1. It is an integrated instrument with small size, electromechanical and atmosphere control;
2. The sample is above the instrument, which is easy to operate;
3. Using a thermally inert miniaturized heating furnace, the sample can be heated linearly from room temperature. The temperature rise control adopts the microcomputer software PID algorithm, which is more accurate than the hardware PID control system;
4. Perfect two-way voltage stabilization and steady flow atmosphere control system;
5. From micro samples to large samples can be satisfied, the maximum sample can reach 200 ㎎;
6. The addition of the airflow adjustment device can minimize the surface weight gain caused by thermal buoyancy during the heating process;
7. The intelligent software and hardware design makes the measurement process complete automatically and draws automatically;
8. The user can use the standard sample to calibrate the instrument for temperature and differential heat to reduce instrument errors;
9. USB or serial communication interface, easy to connect with computer
10. The automatic temperature control software is powerful and flexible, with friendly user interface, rich data analysis and flexible temperature program setting;
9. In the process of collecting samples by the intelligent system, the range can be changed according to the size of the output signal.
