Guide and selection support
Coating testers are used to accurately determine the dry film thickness of coatings. This is relevant in various industries, such as painting, metalworking, or plastic coating. Measurement supports quality assurance and process control in both laboratory and production environments.
Key selection criteria include the measuring principle (magnetic, eddy current, ultrasonic), the material compatibility between substrate and coating, as well as the required measurement accuracy and mobility of the device. In addition, handling—whether stationary or portable—plays a role for the specific application.
LabFinder provides a structured overview of different types and technologies of coating testers to simplify targeted searching and selection for users. This enables the rapid and well-founded identification of suitable solutions for precise coating thickness measurement.
Application and Benefits
Coating testers are used for measuring layer thickness and dry film thickness on the surfaces of various materials. They are central tools for quality assurance in production processes and laboratories, especially in painting, metallic, or plastic coatings. Measurement results help verify compliance with specified coating thicknesses and allow for early detection of deviations.
Selection Criteria
Essential factors when selecting a coating tester include the measurement principle, compatibility with the coating and substrate materials, and the required measurement accuracy. Desired mobility or integration into a production line is also crucial. Operability and availability of supplementary functions such as data recording or interfaces are also relevant.
Variants and Measurement Principles
Coating testers use different measurement methods: Magnetic methods are especially suitable for ferromagnetic substrates, eddy current methods for non-magnetic metals, and ultrasonic-based devices allow non-contact measurement even on non-metallic substrates. This variety enables adaptation to specific testing tasks.
Calibration and Maintenance
Regular calibration is necessary to ensure measurement accuracy and comparability of results. Maintenance includes checking sensors, cleaning measurement surfaces, and updating software if needed. Care instructions from manufacturers support the durability and reliability of the instruments.
Limits of Application
Coating testers are limited to measuring layer thickness and do not directly assess other qualities, such as adhesion, bonding strength, or abrasion resistance. Additional testing methods are required for those characteristics. Highly irregular or structured surfaces can also complicate measurement.

Frequently asked questions
How does a coating tester work?
Coating testers measure the thickness of a coating using various physical principles such as magnetism, eddy current, or ultrasound, depending on the coating and substrate material.
What measurement principles are there for coating testers?
Common measurement principles are magnetic methods for ferromagnetic substrates, eddy current measurement for non-magnetic metals, and ultrasonic measurement for non-metallic substrates.
What should I consider when selecting a coating tester?
Important factors are the measurement principle suited to the material, the desired measurement accuracy, handling (stationary or portable), as well as features for data processing and calibratability.
What are the limitations of coating testers in application?
They only measure layer thickness and do not assess mechanical or adhesion-related properties of coatings. Irregular surfaces can also make measurement more difficult.
How often do coating testers need to be calibrated?
Calibration intervals depend on the device type and frequency of use but should be performed regularly to ensure precise and comparable results.
