Hedon Electronic Developments has introduced a new version of its digital salt meter for steel surfaces.
Salt Measurement 2.0 is designed to provide a price-competitive, eco-friendly solution that complies with ISO standard 8502-9, according to Hedon, a Dutch-based global provider of electronic products for the industrial sector.
The meter is designed to detect and measure invisible contamination from soluble salts during surface preparation, in order to head off later corrosion and paint damage on ships, offshore installations, pipelines, windmills, bridges and other structures.
Features and Design
Hedon says its digital salt meter is fully automated, leaves no room for human error, and uses no consumables. The results are stored in memory and can be used later on a PC to make a report for the coating technical file. The meter also works on curved surfaces.
Many industries have set stringent requirements for maximum allowable soluble salt concentrations for various applications, the manufacturer notes. In order to test for surface cleanliness, the surface contaminants must be extracted and analyzed.
With Salt Measurement 2.0, soluble salts on the surface are dissolved into deionized water, and the solution is tested for conductivity.
Conductivity measurements, recorded in both micro Siemens per centimeter (µS/cm) and milligrams per m2 (mg/m2), correspond to the concentration of dissolved ions in the solution. A high conductivity measurement indicates a high level of dissolved ions and, thus, a high salt contamination on the surface.
Several lease and purchase options are available.
