DEFELSKO

Defelsko is a manufacturer of coating thickness gauges and adhesion testers, founded in 1966 in Ogdensburg, New York, USA. The company specializes in handheld, non-destructive measurement instruments for coating and material thickness, as well as surface profile and environmental testing. Their product families include the PosiTector series (coating thickness, ultrasonic thickness, surface profile, and environmental gauges), the PosiTest series (adhesion testers and coating thickness gauges), and the PosiPen series (magnetic coating thickness gauges). These instruments are used in industries such as automotive, aerospace, marine, metal finishing, and industrial maintenance for quality control and inspection of paints, platings, galvanizing, and other coatings. Defelsko instruments are known for their rugged build, with many models featuring IP-rated enclosures (e.g., IP65 for dust and water resistance), and they are supplied with NIST-traceable calibration certificates. The product range covers measurement ranges from 0 to 150 mils (0 to 3800 microns) for coating thickness, with accuracy specifications such as ±0.04 mils (1 µm) for lower ranges. 3G Electric stocks a selection of Defelsko gauges, including analog and digital models, with integral or cabled probes, and accessories like carrying cases, shims, and protective holsters. The inventory includes standard and advanced body styles, with options for magnetic (ferrous) and non-magnetic (non-ferrous) substrates, as well as ultrasonic thickness gauges for measuring material thickness from one side. 3G Electric supports these products with logistics for global shipping, ensuring that plant engineers, maintenance managers, and procurement specialists can source Defelsko instruments with NIST certification and compatible accessories for their specific measurement tasks.

Frequently asked questions

Common questions about DEFELSKO from 3G Electric.

What is the difference between the Defelsko PosiTector 200 and the PosiTector 6000 series?

The PosiTector 200 is designed for measuring coating thickness on non-metal substrates such as plastic, wood, and concrete, using ultrasonic technology. It measures total coating thickness up to 150 mils (3800 µm). The PosiTector 6000 series, in contrast, uses magnetic induction (for ferrous substrates) and eddy current (for non-ferrous substrates) to measure coating thickness on metals, with a typical range up to 60 mils (1500 µm). The choice depends on the substrate material and coating type.

Does the Defelsko PosiTest GM analog gauge require batteries?

No, the PosiTest GM is a mechanical, analog coating thickness gauge that operates without batteries. It uses a permanent magnet and a calibrated spring mechanism to measure non-magnetic coatings (e.g., paint, galvanizing) on steel substrates. The gauge provides a direct reading on a dial scale, with a measurement range of 0 to 8 mils (0 to 200 µm) and an accuracy of ±0.04 mils (1 µm) up to 0.8 mils. It is supplied with a NIST-traceable calibration certificate and a soft carrying case.

What is the measurement accuracy of the Defelsko PosiTector UTG C1 ultrasonic thickness gauge?

The PosiTector UTG C1 has a thickness measurement accuracy of ±0.001 inches (±0.025 mm). It uses ultrasonic pulse-echo technology to measure the thickness of materials such as steel, aluminum, and plastics from one side. The gauge includes a couplant, protective holster, and soft carrying case, and comes with a NIST-traceable calibration certificate. It is suitable for applications like corrosion monitoring and wall-thickness inspection.

Can Defelsko coating thickness gauges measure on both ferrous and non-ferrous substrates?

Yes, certain Defelsko models are designed for dual-substrate measurement. For example, the PosiTector 6000 FN series (e.g., FN1, FN3) uses both magnetic induction and eddy current principles to measure coating thickness on ferrous (steel) and non-ferrous (aluminum, copper) substrates. These gauges automatically detect the substrate type and switch measurement modes. Models like the FS1-E and FNS3-E are also available with cabled probes for flexibility in tight spaces.

What accessories are included with Defelsko gauge probes like the FN3?

The Defelsko FN3 probe (integral, advanced body style) includes a wrist strap and is supplied with a NIST-traceable calibration certificate. Other probes, such as the FN1, include precision plastic shims for calibration verification. Cabled probes like the FS1-E include a protective lens shield, while the FNS3-E and FS3-E include precision plastic shims or a carrying case. Accessories vary by model, but all probes are designed for use with compatible PosiTector bodies.
