BTK-220 Bresle test kit
Bresle Test Kit
The presence of salts on the substrate can lead to the premature failure of the coating system. Most high performance coating systems require that the substrate be cleaned to a recognized standard before the application of the coating.
Once the bresle patch is applied to the surface to be tested distilled water can be analysed using the conductivity meter before being injected into and then extracted from the bresle patch the required amount of times before being analysed again in the conductivity meter. The difference in the two readings show the conductivity of the water, by multiplying the result by 0.4 the presence of salts expressed in parts per million is shown.

Product description
The BTK-220 Bresle Test Kit includes all the necessary equipment for assessing the level of soluble salts on blast cleaned surfaces prior to coating. Inside the Bresle Test Kit is a conductivity gauge used for the assessment of soluble salt ions as chlorides, sulphates and nitrates. The Bresle Test Kit complies with the ISO standards, describing the Bresle Method, that state that the conductivity is mainly directly proportional to the concentration of dissolved salts in the solution.
Contamination of blast-media
The Bresle Kit is also suitable to determine the contamination of blast-media. This prevents the dissolved salts in the recycled abrasive contaminating the surface being cleaned.
Features
Unique Direct Sampling Procedure (DSP) to ensure high speed and accuracy. Up to 60 times more accurate than other test kits available.
Application areas
Marine coatings, protective coatings, pipeline coatings, paint production, surface finishing, powder coating.
Standards: ISO 8502-6, ISO 8502-9, ISO 11127-6.
