Some of the most critical coating measurements occur in places standard probes cannot access. For complex geometries, internal diameters, grooves, tight corners, and recessed surfaces, a specialized probe is essential. The Nuicon EC770P Pen Probe Coating Thickness Gauge is engineered specifically for these challenges, delivering high-accuracy measurement performance through a slim, durable pen-style probe designed for precision in restricted spaces.





Provides accurate, stable, and repeatable coating measurements even in areas traditional probes cannot reach. Ideal for applications requiring precision inside cavities, narrow features, or complex metal components.
The EC770P features a rotatable 128×128 LCD display and an intuitive menu system, making it simple to operate even when working at awkward angles or in difficult viewing positions.
Designed for reliable readings of non-magnetic coatings on steel and insulating coatings on non-ferrous metals. Ensures accuracy even when the probe is retracted and repositioned.
Automatically identifies ferrous and non-ferrous substrates and applies the correct measurement method without manual adjustment.
Displays maximum, minimum, average, and standard deviation values, helping operators assess coating uniformity and measurement quality.
Options available: For rough surfaces, for high precision, for non-metal substrates, for tight or hard-to-reach areas.

Trust lab-grade precision; featuring 0.1μm resolution and NIST certification for critical aerospace validation.

Get into the tight spots; this pen-style probe measures inside pipes and on curved surfaces others can’t reach.

Master non-destructive testing on plastics and composites with advanced ultrasonic technology.

For advanced analysis when you need to measure the individual thickness of paint, primer, and other layers.

A rugged, all-purpose gauge with auto-detection, perfect for demanding on-site job inspections.
