3nh YT4200-P7 Coating Thickness Gauge (0~1250μm)

3nh YT4200-P7 Coating Thickness Gauge (0~1250μm)

3nh YT4200-P7 Coating Thickness Gauge (0~1250μm) is a digital, high-precision measurement device featuring a separated type probe, specially designed to measure the thickness of insulating coatings (such as paint, powder coatings, plastics, porcelain enamel…) on non-magnetic metal substrates (NFe) like aluminum, copper, brass, and stainless steel.

Product Highlights

• Non-destructive Measurement Method: Helps accurately determine the thickness of paint or plating layers without causing any affection or damage to the sample surface.
• Flexible Separated Probe Design: The probe is connected to the device via an extension cable, allowing users to easily insert the probe into small corners, inner pipe surfaces, or complex machine parts that integrated probes cannot reach.
• High Accuracy and Stability: The probe features high sensitivity, fast response times, and a clear, intuitive display screen.
• Diverse Calibration Support: The device allows for Zero-point calibration, 1-point, or multi-point calibration using the included standard calibration foils, ensuring the highest accuracy for each specific material.
