DeFelsko PosiTector UTG ultrasonic wall thickness gages inspect remaining wall thickness on steel structures, piping, tanks, boiler tubes, pressure vessels, and marine hulls subject to erosion and internal corrosion.
The UTG M probe with Thru-Coat technology measures true metal thickness directly through painted surfaces without removing the protective coating, saving significant time during maintenance inspections.
Selection criteria: wall thickness range, transducer type (UTG C corrosion, UTG M Thru-Coat multi-echo, or UTG P precision thin-wall).
DeFelsko PosiTector SST Soluble Salt Testers for Bresle Method
PosiTector SST soluble salt testers evaluate surface conductivity and calculate soluble chloride salt contamination on blasted steel surfaces per ISO 8502-6 and ISO 8502-9 Bresle patch guidelines.
The patented reusable PosiPatch attaches via a magnetic ring without adhesive residue, providing clean extraction with deionized water and immediate digital calculation of surface density in mg/m² or µg/cm².
Selection criteria: test chamber kit (reusable magnetic PosiPatch, standard adhesive Bresle patches, or flexible latex patches).
DeFelsko PosiTest AT Hydraulic Pull-Off Adhesion Testers
PosiTest AT pull-off adhesion testers measure the adhesion strength of coatings applied to metal, concrete, wood, and other rigid substrates per ASTM D4541, ISO 4624, and AS/NZS 1580.408.5.
Available in manual hydraulic (AT-M) and automated electro-hydraulic (AT-A) configurations, featuring calibrated pull rates, self-aligning quick-coupling actuators, and dolly sizes from 10 mm to 50 mm.
Selection criteria: drive mechanism (manual AT-M or automated AT-A) and dolly diameter (10, 14, 20, or 50 mm) matched to expected adhesion strength.
DeFelsko PosiTest HHD High Voltage Holiday Detectors
PosiTest HHD high voltage pulse holiday detectors detect pinholes, porosity, and voids in non-conductive protective coatings applied to steel pipelines, storage tanks, and structural steel per NACE SP0188 and ASTM D5162.
Featuring a user-adjustable output voltage from 0.5 to 35 kV with integrated crest voltmeter, the unit reliably inspects dielectric coating systems up to 25 mm in thickness.
Selection criteria: coating insulation thickness, test voltage requirements, and electrode type (rolling spring, fan brush, or conductive rubber wand).
PosiTector Universal Gage Platform and Interchangeable Digital Smart Probes
The primary design advantage of the DeFelsko PosiTector line is its unified electronic gage platform.
Every PosiTector gage body accepts all interchangeable probe models manufactured by DeFelsko: 6000 and 200 coating thickness probes, DPM environmental dew point meters, SPG and RTR surface profile sensors, UTG ultrasonic wall thickness transducers, SST soluble salt conductivity cells, SHD/BHI hardness durometers, and GLS gloss meters.
The gage body instantly recognizes connected probes and automatically loads onboard calibration tables, allowing an inspection agency or plant quality department to fulfill multi-parameter inspection tasks with minimal hardware investment.
Gage Body Performance Levels: Standard Features Versus Advanced Analytics
PosiTector gage bodies are available in Standard and Advanced models. The Standard gage body includes a high-contrast color LCD, memory capacity for 1,000 readings in a single batch, and real-time statistical calculations including mean, minimum, maximum, and standard deviation.
The Advanced model is engineered for extensive field surveys and high-volume production quality control: it features an expanded memory of up to 250,000 readings across 1,000 customizable batches, onboard Wi-Fi and Bluetooth connectivity, onscreen help prompts, live charting, histogram displays, and integrated statistical compliance modes per SSPC-PA 2 and ISO 19840 standards.
Metrological Calibration Verification and NIST Traceability Compliance
High measurement accuracy and audit readiness are ensured through DeFelsko certified calibration standards traceable to the National Institute of Standards and Technology (NIST).
Each gage and probe is supplied with an individual Long-Form Certificate of Calibration documenting measured values and uncertainty budgets.
For daily verification prior to inspection shifts, operators utilize certified precision shims and zero plates to perform quick zero offsets or two-point calibration adjustments directly on blast-cleaned production parts, neutralizing surface roughness and alloy composition effects.
Inspection Consumables: Adhesion Dollies, Bresle Patches, and Ultrasonic Couplants
Continuous destructive and non-destructive coating evaluation requires a steady inventory of certified consumables.
We provide timely shipments of precision aluminum and steel pull-off dollies (10, 14, 20, and 50 mm diameters) for PosiTest AT testers, high-shear two-component epoxy adhesive kits, abrasive cutting hole saws, reusable adhesive-free PosiPatch extraction cells and latex Bresle patches for chloride analysis, certified deionized extraction water, and high-temperature ultrasonic couplant gels formulated for acoustic signal transmission.
End-to-End Surface Preparation and Coating Inspection per ISO and ASTM Standards
DeFelsko instruments provide a complete technological workflow for multi-stage quality assurance across marine, pipeline, structural steel, and petrochemical fabrication projects.
The process begins with peak-to-valley surface roughness quantification per ASTM D4417 and water-soluble salt testing per ISO 8502-6 and 8502-9. Before paint application, the PosiTector DPM confirms that substrate surface temperature exceeds dew point by at least 3 °C per ISO 8502-4.
Following coating cure, dry film thickness is audited per ISO 2808 / SSPC-PA 2, pull-off adhesion strength is verified per ASTM D4541, and dielectric holiday detection is completed per NACE SP0188.
PosiSoft Software Suite and Automated Inspection Report Generation
All DeFelsko instruments connect seamlessly to the PosiSoft software suite, available across Desktop applications, PosiSoft.net cloud sync, and the mobile PosiTector App for iOS and Android devices.
