It is essential that the level of contaminates on a surface is measure prior to application of the coating to ensure the quality of the coating and that its optimum lifetime is achieved.
If the coating is applied to a contaminated surface, which is not properly prepared it could fail prematurely resulting in costly re-coating and high maintenance costs.
This kit comes complete with everything you need to comply with ISO 8502-6, ISO 8502-9, The Bresle Method. The Elcometer 135B is a self-adhesive rubber film patch with a sealed compartment used for taking samples of soluble salts.
The Elcometer 138 Bresle Kit includes the Elcometer 138 conductivity meter. The cartridge type sensor can be easily replaced when necessary and displays conductivity in a range of units including: S/cm, S/m, ppm and % salinity.
The Elcometer 138/2 Surface Contamination Kit provides the means for testing invisible surface contaminants.
Measuring the level of contaminants on a surface prior to application of the coating is essential to ensure the quality of the coating and that its optimum lifetime achieved.
Elcometer 135B Bresle Patches are the original Bresle Patches manufactured by the Swedish Standards Institute. Used to determine surface chloride contamination and are self-adhesive rubber film patches with a sealed compartment for sampling soluble impurities from steel surfaces with a suitable solvent.
Chloride ions on steel surface increase the probability that corrosion of the steel will take place even if a protective coating is applied. Chloride ions trapped under a coating in the presence of steel and moisture will form a corrosion cell. This corrosion process will result in premature failure of the protective coating and may cause blistering of coatings in immersion service.
Chloride test strips will indicate the concentration of chloride ions in the sample solution and if the area of sample collection and volume of water is known the concentration can be measured in parts per million or micro-grams per millimeter.
