Surface Contaminants


PosiTector SST Soluble Salt Tester

DeFelsko introduces its new PosiTector SST Soluble Salt Tester for measuring soluble salt contamination on metal surfaces. PosiTector SST is a conductivity probe designed specifically for the Bresle Method of salt testing, and is compatible with any Bresle Patch, including DeFelsko's new PosiPatch and the proprietary DeFelsko Patch.


DeFelsko SST Bresle Method Salt Test Patches

DeFelsko's new PosiTector SST Soluble Salt Test probe offers four Bresle method patch options for measuring soluble salts on surface prior to the application of protective coatings: the economical DeFelsko Patch, the latex Bresle patch conformable to ISO 8502-6, the patented new PosiPatch reusable silcone Bresle-method patch with either a magnetic aluminum ring or their newest Flexible Magnetic Ring.


Flexible Magnetic PosiPatch Ring

DeFelsko's new PosiPatch attaches to steel surfaces using a magnetic ring. Choose either the Standard Magnetic Ring, made of aluminum, for flat surfaces, or the new Flexible Magnetic Ring, for use on pipes and other curved surfaces.

Chlor*Test W Chloride Ion Test Kit for Water & Liquids

ChlorTest W Chloride Ion Test Kits for Water by Chlor*Rid International are simple to use and accurate field test kits for measuring soluble salts in water used for blast cleaning for coatings preparation, or other liquids. Chlor*Rid ChlorTest W Soluble Salt Test Kits are available in 5-test packs or bulk packs of 50 tests for all salt test applications.


TQC Dust Tape Test Kit

The TQC Dust Tape Test Kit allows evaluation of surface cleanliness prior to paint application, in accordance with the principle of ISO8502-3 “Assessment Of Dust On Steel Surfaces Prepared For Painting (Pressure-Sensitive Tape Method). A rigid binder contains a visual comparator, tape, scissors, magnifier, and standardized report forms.


TQC Bresle Salt Test Kit

The TQC Bresle Chloride Test Kit follows the ISO 8502 standard for testing of steel surfaces for surface salts before applying paints or coatings. A sample is collected in a Bresle Patch, from the surface to be coated, and conductivity of the sample is assessed using the TQC Conductivity Meter to calculate total soluble salts in the sample. The Bresle Test can also be used to assess recycled blast media for salt contamination prior to re-use.


DeFelsko's Wireless Bluetooth Printer

NEW! DeFelsko's Wireless Bluetooth® Printer prints stored batches or streams live readings from your PosiTector Advanced gages.


LeadCheck Kit

LeadCheck is a simple-to-use test kit for detection of lead contamination on surfaces. LeadCheck Swabs instantly detect lead as low as 1 microgram on surfaces, the tip turning progressively darker red for higher levels of lead.
