Overview
QLH-225 (200 ℃) ventilation aging test chamber is produced by ZKHS, which is suitable for the heat resistance test of electrical insulation materials and the ventilation aging test of electronic spare parts and plasticized products. The box body is processed by numerical control machine tool, which is beautiful and generous in shape and easy to operate.
Features
1. The box body is processed and formed by numerical control machine tool, with beautiful and generous shape, and adopts no-reaction handle, which is easy to operate.
2. The inner tank of the box is made of imported stainless steel (SUS304) mirror plate argon arc welding.
3. The shell of the box is sprayed with A3 steel plate to increase the appearance texture and cleanliness.
4. Adopt an intelligent program microcomputer controller with temperature control protection, with timing function, accurate and reliable temperature control.
5. Large observation window with lighting, using tempered Glass, you can clearly observe the situation in the box.
6. The hot air circulation system consists of a fan that runs continuously at high temperature and a special air duct to ensure uniform temperature in the working room.
7. The device is equipped with a low-speed turntable.
Principle
The test chamber is driven by a high temperature and low noise motor and a multi-leaf centrifugal wind wheel through a hot air circulation system. It runs continuously at high temperature to ensure uniform temperature in the working room. Microcomputer integrated controller is used for precise temperature control and timing to realize the ventilation aging process.
Applications
Electrical insulation materials heat resistance test, electronic parts, plasticized products ventilation aging test
