Cyclic Corrosion Test Chamber Digital

The 4B Testing Equipments Pvt. Ltd. Cyclic Corrosion Test Chamber is an advanced environmental testing system designed to simulate real-world corrosive environments by combining salt spray, humidity, drying, condensation, and programmable cyclic corrosion testing within a single chamber. The equipment is ideal for evaluating the corrosion resistance and service life of coated metals, painted surfaces, electroplated components, automotive parts, aerospace materials, fasteners, and industrial products.

Unlike conventional salt spray testing, the Digital Cyclic Corrosion Test Chamber reproduces natural environmental conditions by automatically switching between different exposure cycles. This provides a more accurate prediction of long-term corrosion performance and coating durability.

Description

The chamber is equipped with a PLC-based HMI Touch Screen Controller that allows users to create, store, and execute customized corrosion test programs. The intelligent control system automatically manages salt spray, humidity, drying, temperature, and test duration, ensuring highly accurate and repeatable results.

Manufactured using corrosion-resistant FRP (Fiberglass Reinforced Plastic) or PP (Polypropylene) construction, the chamber offers excellent durability and long service life even under continuous operation.
