Metal Coating Thickness Measurement Solutions

Coating thickness gauges are primarily used in the metal processing industry to measure the thickness of coatings or plating, which is crucial for ensuring product quality and performance. However, some issues may arise during use. Below are some common problems and their solutions.

1. Inaccurate Measurement Data

Inaccurate measurement data from a coating thickness gauge can result from various factors. For instance, outdated equipment, devices not designed for the metal processing industry, or damaged equipment may cause inaccurate readings. Additionally, if the probe is placed too close to the edge, hole, cavity, or other sections with variations in thickness, it can lead to measurement errors.

2. Factors Affecting Measurement Accuracy

Several factors can influence the accuracy of coating thickness measurements, including:

lBoundary Distance

lSubstrate Surface Curvature

lMinimum Substrate Metal Thickness

lSurface Roughness and Cleanliness

lProbe Measurement Pressure

lExternal Magnetic and Electromagnetic Fields

lSubstrate Residual Magnetism

lFerromagnetic and Conductive Components in the Coating Material

lUnderstanding these factors helps in taking appropriate actions to improve measurement accuracy.

Solution: Choosing the Right Equipment

To address these industry challenges, it may be necessary to select a device with precise measurement algorithms and automatic substrate recognition. The Qindu P-210 Coating Thickness Gauge is a newly developed model by Qindu, specifically designed for the metal processing industry. With years of R&D improvements, the P-210 offers automatic substrate material identification and a fast 0.3-second measurement time. It delivers high measurement accuracy and reliable results. The device also features an easy calibration method—just press and lift the probe to quickly calibrate the instrument. Additionally, Qindu has implemented design measures to counter other factors that affect measurement accuracy.

Qindu Industrial Coating Thickness Gauges: Applications and Benefits

Qindu Industrial Coating Thickness Gauges are widely used in various industrial fields, including automotive manufacturing, coating industries, electronics, and the paint industry. These instruments not only provide accurate coating thickness measurements but also help users assess the condition of materials and their material properties.

Working Principle

The working principle of coating thickness gauges primarily involves two types of measurements: magnetic measurement and non-magnetic measurement. For non-magnetic coatings on magnetic metal substrates, magnetic measurement methods are typically used. For non-conductive coatings on non-magnetic metal substrates, non-magnetic measurement methods are employed. This non-destructive testing technique reveals material information beneath the coating, helping users accurately evaluate the condition and material characteristics of the substrate.

Applications

Automotive Industry:

Coating thickness gauges play a crucial role in automobile repair, detailing, and used car transactions. They help professionals accurately determine the original condition of the paint, detecting any signs of respraying, touch-ups, or paint repairs.

Coating Industry:

Coating thickness gauges are widely used to measure coating thickness, ensuring the quality and reliability of the applied coatings.

Aerospace:

Coating thickness gauges are applied to measure the coating thickness on aircraft bodies, engines, and other components, ensuring the safety and performance of aircraft.

Electronics Industry:
