Air-exchange aging test chamber-Linpin Instruments

Product Features

Product application:
The chamber of the air-exchange aging test chamber is suitable for heat resistance testing of electrical insulation materials and ventilation aging testing of electronic components and plastic products.
Chamber structure:
The chamber of the air-exchange aging test chamber is processed and formed by a CNC machine tool, with an aesthetically pleasing, generous, and novel design. It also features a non-reaction handle for easy operation. The inner lining of the chamber is made of imported high-grade stainless steel (SUS304) plate or fabricated by TIG (tungsten inert gas) welding with 304B stainless steel. The outer shell is made of A3 steel plate with plastic spraying, enhancing the appearance and cleanliness. The air-exchange aging test box is equipped with an intelligent programmable microcomputer controller with temperature control protection, featuring a timer function for precise and reliable temperature control. A large observation window with a lighting lamp keeps the interior bright, and the use of tempered glass allows for a clear view of the conditions inside the chamber at any time. The hot air circulation system consists of fans that can operate continuously at high temperatures and specially designed air ducts, ensuring uniform temperature distribution within the working chamber. The aging box is equipped with a low-speed rotating turntable. The chamber insulation uses superfine glass fiber insulation cotton to avoid unnecessary energy loss. The duration and frequency of air exchange can be set arbitrarily.
Compliance with standards:
JB7444-94 GB/T3512-01

Industry News

Cold and heat shock test chamber operation you understand?

Cold and thermal shock test chamber on the market is divided into two categories, a two-compartment type, including high-temperature region and low-temperature region, the test object were in two different temperatures in the area of the test, hot and cold alternating test; the other is a three-compartment type, in addition to high-temperature and low-temperature areas, there is also a test area, and the two-compartment different is that the three-compartment does not need to be directly in the test area for the test, only need to be through the air compression method

Troubleshooting Temperature Cycling Test Chambers: Are You Using the Right Methods?

When a temperature cycling test chamber malfunctions, how should you troubleshoot it? Have you identified the correct diagnostic approach? Mastering the right methods can help quickly locate the issue and restore functionality more efficiently.

Are You Maintaining Your Constant Temperature and Humidity Test Chamber Correctly?

If a constant temperature and humidity test chamber malfunctions due to improper operation or lack of maintenance, it will not only affect the progress of work but also incur costs much higher than those of regular maintenance.
