PosiTector SST Soluble Salt Tester


DeFelsko Corporation is pleased to introduce its new PosiTector SST Soluble Salt Tester, the first conductivity probe designed specifically for measurement of total soluble salts using the Bresle Method according to ISO 8502 - 6: Preparation of steel substrates before application of paints and related products -- Tests for the assessment of surface cleanliness -- Extraction of soluble contaminants for analysis -- The Bresle method.

 

Salt contamination on surfaces or in blast media can cause degradation of the surface over time, and result in early coatings failure. Detection of soluble salts prior to coatings application is necessary to allow the paint contractor to remove salt contamination from the surface before applying protective coatings. The PosiTector SST Conductivity Probe features a test cell optimized for the range, resolution, and test volume of the Bresle test method for soluble salt contamination. PosiTector SST measures the temperature, volume, and change in conductivity of the sample, calculates surface density, and records the time and duration of the test, in accordance with ISO 8502-6 test method.

 


The PosiTector SST is ideal for:

  • testing substrates for the presence of soluble salts in accordance with ISO 8502-6,9 (Bresle method)
  • testing blast media in accordance with ASTM 4940 and ISO 11127-6* (determination of water-soluble contaminates in abrasives by conductivity measurement)
  • testing the conducitivity of water within the range of 0 - 500 µs/cm

* ASTM 4940 - Standard Test Method for Conductimetric Analysis of Water Soluble Ionic Contamination of Blast Cleaning Abrasives
ISO 11127-6 - Preparation of steel substrates before application of paints and related products -- Test methods for non-metallic blast-cleaning abrasives -- Part 6: Determination of water-soluble contaminants by conductivity measurement

PosiTector Soluble Salt Tester probe can be used with either the Standard or Advanced PosiTector gauge body, and with virtually any Bresle patch.

  • PosiTector body compatible with all PosiTector probes: SST, 6000, 200, RTR, SPG, DPM, SHD, UTG - one gauge converts with a probe swap from soluble salt tester to coating thickness gauge for metal or non-metal substrates, surface profile gauge, replica tape reader gauge, dewpoint meter, Shore hardness durometer, or ultrasonic wall thickness gauge

 

 

DeFelsko offers three Bresle-method salt test patches to choose from:

 

Bresle Method PosiPatch

The revolutionary PosiPatch is a non-adhesive, silicone patch that adheres to steel surfaces using a magnetic ring. An air-permeable membrane automatically removes air from the patch while the water is injected. A flexible dispensing tip fits into the port in the PosiPatch, eliminating the use of sharp needles. PosiPatch is also re-usable, making it a most economical option among the Bresle method patch options available on the market today.

DeFelsko's new PosiPatch features:

  • Measures salt contamination in accordance with ISO 8502-6.9
  • Magnetic ring attaches PosiPatch to steel; no foam or adhesive residue to clean. Ideal for flat surfaces and diameters over 40 inches / 100 cm
    Two rings are available: original aluminum PosiPatch magnetic ring, suitable for flat surfaces, and the new Flexible PosiPatch magnetic ring, that will adhere to pipe of 4" diameter:

 

 

 

 

 

 

 

new Flexible Magnetic Ring inside and outside 4" pipe.

 

  • Automatic air removal through a water-tight, air-permeable membrane
  • Safe, flexible dispensing tip mates with a port in the PosiPatch. No sharps, no needles!
  • Reusable, patent-pending PosiPatch saves time & money - with no adhesive, the patch is not torn when removed from the surface. Simply rinse the PosiPatch with de-ionized water and use for more testing. (DeFelsko believes 10 tests is a conservative estimate of the number of uses possible with a single PosiPatchused according to manufacturer's directions.)
  • Easy to use in any orientation
  • Available in a PosiPatch Starter Kit, containing everything needed to use the PosiPatch with other soluble salt testing kits. (2 syringes, 2 dispensing tips, 5 PosiPatches, & magnetic ring.)

            

 

 

 

 

 

 

 

 

Bresle Method DeFelsko Patch

The Bresle Method DeFelsko Patch is an economical polyurethane patch with low-tack adhesive for easy removal from the surface, leaving no residue to clean up. The DeFelsko Patch works on most surfaces, and is more economical to purchase than latex patches.

  • measures salt contamination in accordance with ISO 8502-6,9
  • low-tack adhesive for easy patch removal & no residue left on the surface
  • works on nearly any material or surface geometry.
  • latex-free
  • economical
  • easy-to-use in any orientation
  • Available in packages of 25           

 

 

 

 

Latex Bresle-Method Patch

Latex Bresle method patch conforms to ISO 8502-6. Features easy-open tabs and low-tack adhesive for easy removal.

 

PosiTector SST Soluble Salt Tester is available as a Standard or Advanced PosiTector gauge with nylon carrying case, PosiTector SST probe only to pair with your existing PosiTector gauge body, (Standard bodies with coloured display and Advanced gauge bodies with serial number 730000 or higher) , or in a kit including the probe, Standard or Advanced PosiTector body, and your choice of patch types (PosiPatch, DeFelsko Patch, or standard Latex adhesive patch) with the necessary accessories to use the gauge.
