Video summary

Elcometer Soluble Salt Profile Gauge: Advanced Chloride Measurement on Pre-Coated Surfaces

The new Elcometer soluble salt profile gauge measures 252 individual readings per test to reveal the actual distribution of chloride contamination, rather than just reporting a single average value like traditional Bressler patch and filter paper methods
The gauge provides selectable data output modes (B mode for Bressler-equivalent results, E mode for filter paper-equivalent results) and includes 2D and 3D visualization, four-quadrant Bressler-sized area breakdowns, and pass/fail analysis against user-defined limits
Peak contamination levels are more relevant to corrosion risk than averages, since chloride salts crystallize randomly during moisture evaporation and form isolated concentrations rather than uniform layers
The test time is reduced to approximately 2.5 minutes, consumable costs per test are lower than Bressler patches, and payback of the higher initial equipment cost occurs within 320 tests when labor costs are included (roughly 3 months at 3 tests per day)
The gauge offers integration with Elcometer's data management software for automated report generation, includes a magnetic pad accessory to prevent paper evaporation and displacement, and has received recognition including NACE Product of the Year 2017

Craig Woolhouse from Elcometer presented advances in measuring soluble salt contamination on steel surfaces before coating application. Inadequate surface preparation causes 75% of in-service coating failures, and chloride salts are the most common contaminant. Two traditional methods—Bressler adhesive patches and saturated filter paper tests—both provide only single average values despite salt contamination forming in randomly distributed crystallized concentrations. The new Elcometer profile gauge measures 252 individual sensor readings per test, creating detailed maps that reveal where peak contamination exists. The gauge can display results equivalent to either traditional method, show variation across four Bressler-sized areas, or present data as 2D and 3D heat maps and pass/fail compliance graphics. A magnetic pad accessory reduces water evaporation during testing. The test takes 2.5 minutes with lower per-test costs than Bressler patches and integrates with Elcometer reporting software.
