Introducing the PosiTector SST

Abrasives Test Kit


DeFelsko is pleased to announce the new Abrasives Test Kit for measuring the concentration of soluble salts in blast cleaning abrasives in accordance with ASTM D4940 and ISO 11127-6. The Abrasives Test Kit is ideal for use with the PosiTector SST Soluble Salt Tester and other conductivity meters.


To accommodate the new test kit, the measurement range of the PosiTector SST has been increased from 0 - 500 ÁS/cm to 0 - 1500 ÁS/cm. Existing probes can display measurements within the increased range after a gage update, but only probes shipped after March 12, 2018 are calibrated over the extended range, as reflected on the Certificate of Calibration. 



  • Quickly test abrasives for soluble salt contamination in the field or in the laboratory
  • Specifically designed for ASTM D4940 and ISO 11127-6
  • Includes everything required to measure abrasive contamination using a PosiTector SST or other conductivity meter
  • Portable - includes a durable, hard shell case
  • Includes certified conductivity standard (calibration solution) to verify meter accuracy. Certificate of Analysis included.
