Salt Contamination

Colourless soluble salts may be present in pits within the substrate after blast cleaning. This can accelerate corrosion and is referred to as salt contamination


Soluble Salt Testers measure the concentration of soluble salts on metal surfaces.

The PosiTector SST Soluble Salt Tester is a salt contamination gauge. It measures the concentration of soluble salts on metal surfaces. And works in accordance with ISO 8502-6, 8502-9. Features of the tester include an intuitive step-by-step interface that guides users through the Bresle method and automatic computation of surface density of salt. It is compatible with the Defelsko adhesive patch, latex adhesive patch and PosiPatch. The innovative PosiPatch is a non-adhesive reusable patch. The patch adheres to steel surfaces using magnetic ring.


Use the PosiTector SST Abrasive Test Kit to measure the concentration of soluble salts in blast cleaning abrasives with ease and simplicity. The standard test method for conductimetric analysis of water-soluble ionic contamination of abrasives, conforming to ASTM D4940. For use with the PosiTector SST or any existing conductivity meter.
