PosiTector SST
Model No. :
Brand : Defelsko
The PosiTector Soluble Salt Tester is a high-precision, purpose-built instrument for measuring the concentration of soluble salt contamination on metal surfaces using the standardized Bresle Method (). The dedicated conductivity probe and specialized software guides the user through the test procedure, displaying test duration, sample temperature, conductivity (), and automatically calculating the final surface density (). As part of the platform, this meter ensures accurate and traceable pre-coating cleanliness measurements vital for preventing premature coating failure.

FAQs
What is the Bresle Method and why is it used?
The Bresle Method is a standardized surface extraction technique used to determine the concentration of soluble salts on a surface. It is critical because salts are hygroscopic (attract water) and must be removed before coating application to prevent osmotic blistering and sub-film corrosion.
Does the PosiTector measure individual salt ions like chlorides?
The measures the total electrical conductivity of the test solution. Following the calculation, this is converted into a total surface density of soluble salts (typically expressed as ), not the concentration of specific ions.
How is the accuracy of the PosiTector verified?
The instrument is supplied with a Long Form Certificate of Calibration traceable to . Field accuracy is verified using the included Certified Conductivity Standard (a calibration solution) to ensure the probe is performing within tolerance before beginning any critical testing.
Can the PosiTector be used with different types of Bresle patches?
Yes, the system is fully compatible with any Bresle-type patch, including (reusable magnetic patches), Adhesive Patches, and Latex Patches. The gauge’s adjustable settings allow for different patch volumes, ensuring accurate density calculation regardless of the patch used.
What information does the automatically store in memory for each test?
For each test, the saves all required data, including the Date and Time, Test Duration, Initial and Final Sample Temperature, the Increase in Conductivity, and the automatically calculated Surface Density of the soluble salts.
