Gaurav Malhotra

The Korrox IV salt spray testing chamber is one of the widley used laboratory testing instruments in the automotive and metal industry to test the corrosion resistance properties of different materials. This highly accurate lab testing equipment designed by the experts at Presto has been embedded with next-gen features that make it easy for users to conduct salt spray tests on the materials. One crucial feature that plays a significant role in ensuring the accuracy of testing results is the air purge mechanism.

The air purge embedded in this high-quality salt spray chamber will easily maintain the optimal environment within the chamber by automatically settling down the fog created by the presence of NaCl salt. In this blog, we will discuss brief information about the Presto salt spray testing chamber Korrox IV Magnus series and the purpose of the air purge mechanism in this testing equipment.

Introduction to Korrox IV Magnus Series Computerized

Korrox IV Magnus series computerized model is HMI based touch screen model that is useful in testing the corrosion-resistant properties of metals and their related products. It offers a salt spray test mode, allowing users to set parameters tailored to their test samples. The chamber incorporates a corrosion-resistant PT-100 sensor and a solid-state digital Programmable Temperature Controller for accurate temperature control.

One of its standout features is the program profile, enabling users to select test parameters and execute tests effortlessly. Besides this, users can also monitor the current test status in real time with the help of this lab testing equipment. Constructed with a robust triple-wall fibre-reinforced body, the chamber is not only durable but also ensures easy placement of testing samples.

Now, let us discuss briefly the features of this high-quality lab testing instrument.

Purpose of air purge in Korrox IV Magnus series computerized

During salt spray testing, a corrosive saltwater (NaCl solution) mist is sprayed in the testing chamber can lead to the buildup of salt deposits and corrosive residues on the chamber's internal surfaces.

This automated function is designed to effectively reduce the fog and mist generated within the chamber during testing, particularly when NaCl (sodium chloride) is present.

The air purge system automatically activates to clear the chamber environment, ensuring the safety of the systems and preserving the integrity of nearby materials during salt spray testing.

Hence, the air purge mechanism works diligently to settle down unwanted elements prior to initiating an experiment, guaranteeing optimal purity levels within the chamber.
