PosiTest LPD

PosiTest Low Voltage PinHole Detector OUT NOW!

By | News

DeFelsko announces the new PosiTest® LPD Low voltage Pinhole Detector. It uses a wet sponge to detect holidays, pinholes and other discontinuities on metal and concrete substrates without damaging the coating. Supplied in a rugged inspection case, the easy-to-use PosiTest LPD includes everything needed for testing.


*Lightweight, ergonomic design – while most other devices are box-shaped, the PosiTest LPD was specifically designed to fit comfortably in the hand with a balanced weight distribution

*4 voltage output options conform to international standards

*Automatic self-test verifies voltage calibration

*Regulated voltage outputs will not drop under load

*GroundSense™ visibly reassures the user that the instrument is properly grounded

*Common threads and connectors allow for use with existing paint roller extensions

*Weatherproof, dustproof and shockproof – meets or exceeds IP65

*Long Form Certificate of Calibration included

Introducing The PosiTector 6000 FNDS Probe

By | News

DFT Instruments is pleased to announce a new addition to the PosiTector series of coating thickness gauges, the PosiTector 6000 FNDS probe for duplex coating systems applied to steel substrates. The PosiTector 6000 FNDS probe simultaneously measures and displays the individual layer thicknesses of zinc and paint in a duplex coating system.

PosiTector 6000 FNDS

PosiTector 6000 FNDS Probe Features

• Measures and displays the individual layer thicknesses of zinc and paint in a duplex coating system with a single reading
• Ideal for measuring the three types of zinc used in duplex coating systems – hot-dip, electro and zinc spray metallizing (thermal spray zinc)
• When taken out of duplex mode, the instrument can be used as a conventional ferrous/non-ferrous gauge to measure the thickness of coatings on ferrous or non-ferrous metal substrates
• Scan mode – Take continuous readings without lifting the probe (Advanced models only)
• Compatible with all PosiTector Advanced and PosiTector Standard gauge bodies with a color display. Simple gauge update required.

Positector Award

PosiTector® Interchangeable Probes

By | News

DeFelsko’s PosiTector® Interchangeable Probes for inspection instruments has been named a Materials Performance Corrosion Innovation of the Year.

The American designed and manufactured PosiTector body accepts all interchangeable probes including coating thickness (6000/200/PC), environmental (DPM), surface profile (RTR/SPG), and ultrasonic wall thickness (UTG) probes.

This innovation allows quick and easy conversion from a coating thickness gage to a surface profile gage, dew point meter or ultrasonic wall thickness gage with a simple probe change. Each probe retains its own unique calibration information allowing for full probe interchangeability, an industry first.

The MP Corrosion Innovation of the Year Awards showcase progressive technological developments in all aspects of corrosion prevention and mitigation and recognize the innovators who have created revolutionary solutions to combat corrosion and protect vital assets from its damaging effects.

Winners were announced at the recent Corrosion 2014, NACE International’s leading corrosion conference and expo.

David Beamish, DeFelsko President, was on hand to proudly accept the award on behalf of the entire DeFelsko staff located in Ogdensburg, New York.

“We are very honored that a panel of leading experts in the field of corrosion chose our interchangeable PosiTector probes as the most innovative product,” said Beamish, “A sincere thank you to all who voted for us as we continue to pioneer new instrumentation for inspectors.”
