The basic principle involves filling the chamber with a saline solution, typically 5% sodium chloride (NaCl) dissolved in distilled water. This solution is then atomized by a nozzle into a fine mist within the chamber, where test specimens are exposed for a specified duration, which can range from a few hours to several days or more, depending on the test standard or specific research requirements. https://www.pacorr.com/product/salt-spray-tester-manufacturers-suppliers/ Facebook: https://www.facebook.com/pacorrtestinginstruments Twitter: https://twitter.com/Pacorr_testing Instagram: https://www.instagram.com/pacorrtesting Linkedin: https://www.linkedin.com/in/pacorr
