The performance of the compressor in a high-low temperature alternating test chamber directly affects the efficiency of the equipment and the test results. Therefore, customers should choose a high-quality compressor to enhance the device's performance. So, how can you determine whether the compressor in the test equipment is good or bad?

Dust testing, codified in GB/T 2423.37 and IEC 60068-2-68, is now mandatory for proving the sealing integrity and reliability of military, automotive, photovoltaic and rail-transit products. Direct test outlays—consumables, energy, labour and depreciation—seldom exceed one to three per cent of the selling price, yet hidden expenses triggered by poor chamber selection—repeat tests, invalid data or after-sales downtime—can leap to eight to twelve per cent.

There are many important considerations when selecting and using a formaldehyde/VOC environmental test chamber. How many of these are you aware of? Today, we’ll share a few key points—have you noticed them?

Salt-spray corrosion testing is the core means of evaluating the resistance of materials and their protective coatings to chloride-containing environments. The test itself only provides an accelerated corrosion “stimulus”; the real technical value lies in the scientific evaluation of the test results.

In many production workshops of enterprises, constant temperature and humidity test chambers are often indispensable pieces of equipment. However, many operators tend to overlook the daily cleaning of these devices during use, leading to a rapid accumulation of grease and dust on the equipment.
