|The Elcometer 138/2 Surface Contamination Kit, provides a quick and easy method of measuring surface contaminants. It comes supplied with test strips to measure:
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 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.
By using the Elcometer 135A Bresle Sampler and various test strips supplied, the Elcometer 138/2 Surface Contamination Kit provides a low cost, simple method of measuring the salt, pH, chloride and iron (ferrous ion) concentration on a test surface in accordance with ISO 8502-6.
Chloride Test Strips
The chloride test strips will indicate the concentration of chloride ions in the sample solution and if the area of sample collection and the volume of water is known the concentration can be measured in parts per million or micrograms per millilitre.
Iron Test Strips
pH Test Strips
The presence of these contaminants can either be detected in a solution washed from the surface or by putting a wet ph Test Strip on to the dry surface. pH does not measure the concentration but it does indicate how acidic or alkaline the surface is. Alkaline surfaces are normally associated with either concrete surfaces that are to be coated or steel re-enforcement bars buried in concrete.
