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 gage also features an onscreen interface that guides users through the Bresle test method. The automatic storage of a background (blank) measurement prforms multiple tests. The unit displays test duration, sample temperature, conductivity (µS/cm) and surface density (mg/m2 or µg/cm2). The device resists solvent, acid, oil, water and dust, and is weatherproof. It is also shock-absorbing, having a protective rubber holster with belt clip. There is a two-year warranty on the gage body and probe. A long-form Certificate of Calibration showing traceability to NIST is included, and there is a certified conductivity standard (calibration solution) to verify probe accuracy, certificate included. The device features automatic temperature normalization and sample temperature reporting, and conforms to national and international standards including ISO, NACE, SSPC, IMO and US Navy. The PosiTector body accepts all PosiTector SST, 6000 III, 200, RTR, SPG, DPM, SHD and UTG probes, easily converting from a soluble salt tester to a coating thickness gage, surface profile gage, dew point meter, Shore hardness durometer or ultrasonic wall thickness gage.
