The PosiTector® SST Soluble Salt Tester measures the concentration of soluble salts (salt contamination) on metal surfaces in accordance with ISO 8502-6, 8502-9. The large, easy-to-read color LCD displays test duration, sample temperature, conductivity (µS/cm) and surface density (mg/m2 or µg/cm2). Easy 1-2-3 gage interface guides users through the Bresle test method.
