TQC Sheen Probes for PosiTector 6000 – Ferro & Non-Ferro

The TQC Sheen Probes for the PosiTector 6000 series offer a versatile and robust solution for measuring coating thickness across a wide variety of metal substrates. Whether you need to measure a few microns of paint or several millimeters of protective coating, there is a probe in this range to suit your application. With options for ferrous, non-ferrous, and combined (FN) materials, these probes work in combination with the PosiTector 6000 to help ensure consistent coating quality and compliance with industry standards.

Why Coating Thickness Testing Matters

Accurate coating thickness measurement is critical in industries where performance, longevity, and regulatory compliance are essential. An under-applied coating can lead to premature corrosion or product failure, while an overly thick layer may result in unnecessary material costs or mechanical issues. By using the appropriate probe for your substrate and coating type, you can verify application quality, optimize production processes, and extend the service life of your products.

How to Choose the Right Probe for Your Application:

Identify your substrate material

• Choose F for ferrous (steel, iron)
• Choose N for non-ferrous (aluminum, copper, etc.)
• Choose FN for dual (ferrous/non-ferrous or unknown)
• Choose FNDS for duplex coatings (e.g., paint over galvanization)

Determine the coating thickness range

• Standard: Up to 60 mils (1500 μm)
• High-range: Up to 500 mils (13 mm) or more
• Select a probe that matches or exceeds your maximum expected thickness

Consider the measurement environment

• Integral probes are compact and ideal for tight or mobile use
• Cabled probes provide flexibility for hard-to-reach areas
• Xtreme™ probes are built for harsh or high-temperature conditions

Account for part geometry and accessibility

• Use angled probes (0°, 45°, 90°) for curved or confined surfaces
• Microprobes are ideal for small or precision-critical areas
• Extended-length cables are available for large structures or remote access

How to Use

These probes are designed for seamless integration with the PosiTector 6000 coating thickness gauge. Simply connect the appropriate probe—either built-in or separate—to your PosiTector gauge or SmartLink device. Place the ruby-tipped probe on the coated surface to take an instant, non-destructive measurement. The probe automatically compensates for substrate type and curvature, ensuring precise results even on irregular or complex surfaces.

Selecting the right probe depends on your specific use case. Begin by identifying the substrate material (ferrous, non-ferrous, or both) and the expected coating thickness range. Consider the shape and accessibility of the test surface—tight areas or unusual geometries may require an angled or mini probe. For high-temperature environments or thick coatings, specialized probes such as the FHXS or FKS series are available.

Smart Connectivity and Flexibility

Each probe is compatible with the PosiTector SmartLink, a wireless device that connects to your smartphone or tablet via Bluetooth. With the free PosiTector app, users can record, store, and share measurement data instantly—turning the probe and your mobile device into a fully functional digital gauge. This flexibility is especially useful for fieldwork, inspections in tight spaces, and applications that require remote data logging or documentation.

Designed for Every Scenario

TQC Sheen’s wide range of probe options includes straight, rectangular, and 90° angled heads, as well as standard and extended measurement ranges—from as little as 0 to 1500 µm, up to 63.5 mm. There are even probes designed specifically for duplex coatings, which can measure the thickness of individual paint and galvanization layers in a single reading. This level of versatility ensures that professionals across industries can find the right solution for their unique needs.

Built for Durability

Each probe is constructed with durability in mind, featuring a strong ruby-tipped sensor that resists wear even after thousands of readings. Cable-mounted probes are built with high-quality materials and are available with extended cable lengths—up to 75 meters—making them ideal for large-scale or hard-to-access surfaces such as storage tanks, pipelines, or structural components.
