Apart from that while performing thesalt mist corrosion test, the sample should not be placed too close to the walls. Otherwise, it would give uneven observations. It comes with a touch screen for operation and communication ports for data logging and transferring.

Salt spray chamberhas become an important machine in comparative analysis. To perform the test, the specimen are inserted in the salt laden fog for certain number of hours. The number of hours can be referred from testing standards or internal standards setup by the industry. The components can be tested before and after treatment with coating. This machine helps in analyzing improvement in performance of the specimen after coating is applied. The fog created by the atomizer has upto 5% of NaCl which is much more than sea water composition. For testing of components to be used at marine atmosphere, this can be considered as the best tool.
