SUGA Combined Cyclic Corrosion Test Instrument CYP-90

Its mission: To serve as the truly global testing model

CYP-90 is an accelerated corrosion test apparatus for metallic materials and coatings capable of salt spray, dry, wet, or ventilation tests either singularly or in cycles. CYP-90 is used as the standard model to be able to conduct cyclic tests specified in JIS, JASO, and ISO. It can simulate accelerated with outdoor exposure. CYP-90 is the most cost-effective combined cyclic corrosion test apparatus. The reference specimens specified in ISO 9227:2006 are used to verify its performance. CYP-90A(for acid rain cycle test),CYP-90D(including salt water immersion test)CYP-90L(30℃ spraying test of anticorrosive paint) and other models are also available optionally.
