When encountering malfunctions in the sand and dust test chamber, how should they be addressed? Is it necessary to contact after-sales service? In fact, some issues can be initially troubleshooted by the customer, such as the following scenarios.

Previously, we introduced some common problems with high and low temperature test chambers. Today, we will discuss the issue of slow cooling in the test equipment, which may be caused by malfunctions in the refrigeration system.

A salt spray test chamber is a device used to evaluate the corrosion resistance of product surfaces, widely applied in material research across various industries and academic institutions.

Thermal shock testing chambers are used to evaluate how materials perform under rapid, extreme temperature changes (from very high to very low temperatures in seconds). These chambers are widely used in industries such as electronics, plastics, and metals to test thermal expansion and contraction effects.

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.
