Want to know how automotive parts survive years of salt, humidity, and road spray? In this video, we demonstrate a PLC/PC-controlled composite salt spray test chamber in action. Watch how it simulates salt fog, acid fog, and alkali fog environments, maintains 95%RH, and runs ASTM B117 tests from 48 to 1000 hours. See the spray system, safety protections, and real corrosion results on metal and coated samples.
