Coating Thickness Meter TOP-CHECK
TOP-CHECK - The unique Coating Thickness Meter with integrated swivel-mounted probe
With the integrated, world-wide unique 90° swivel-mounted probe of the List-Magnetik TOP-CHECK coating thickness meters, you always carry out precise measurements. The compact, lightweight devices are barely larger than a probe and are therefore ideal for on-site applications in areas that are difficult to access. For interference-free measurements in harsh environments, the handy metal housing is splash-proof, in accordance with IP 64. Optionally, we also offer coating thickness tester equipment with flow-water protection. The measuring probe has a wear-resistant ruby probe pole for a long service life with frequent measurement on rough surfaces.
The coating thickness gauges are very easy to use, with the press of a single button, and the self-explanatory multilingual menu.
Quality in the coating thickness measurement
A coating thickness meter is usually used in the quality assurance of coating processes, for example to determine the paint thickness of a paint job, in the testing of vehicles or steel structures, in fire protection (determination of the layer thickness of steel doors). It is not only a paint thickness gauge, but also gumming, anodizing and galvanic coatings can be measured.
Combined probe with magnetic-inductive measuring method and eddy current method
TOP-CHECK Dual has a combined probe that measures insulating layers of paint, varnish, plastic, rubber, ceramics and galvanic coatings (except nickel) in a magnet-inductive measuring method. The device is used on iron and steel subsoil. It is also suitable for measuring insulating layers, using the eddy current method, on non-ferrous metals such as aluminum, brass, copper, bronze and non-magnetic stainless steels, according to ISO 2178 and ISO 2360. TOP-CHECK FN is the device version without data logger and Bluetooth interface.
Measure insulating layer thicknesses on iron and steel
TOP-CHECK Ferro is ideal for iron and steel substrates. The device measures layers of lacquer, paint, plastic, rubber, ceramic, zinc and galvanic coatings (except nickel) according to ISO 2178. TOP-CHECK FE is the device version without data logger and Bluetooth interface.
Measurement data on PC and mobile device through Bluetooth Low Energy interface
To further process your measurement data, you can couple your TOP-CHECK with mobile Android and iOS devices. Or you can communicate with a Windows PC. Bluetooth Low Energy (BLE) technology makes this possible. With the TOP-CHECK BLE App, you can manage projects and assign measurement points on a photo. The measurement results can be statistically evaluated and graphically displayed. The app for Android, iOS and Windows is free.

TOP-CHECK Service tool
The free Windows app TOP-CHECK SERVICE is available on our homepage. You can use it to install additional language packages (besides German and English) on your TOP-CHECK Dual or TOP-CHECK Ferro. You can use it to set the time on your device that will be used during data transfer.
If there is a malfunction of the device, you can read data from the device, which will help our technicians in telephone support to analyze it. Thus, we may be able to remedy the situation without you having to send in the device and lose time.
The application runs on Windows 10 and Windows 11. Older Windows versions are not tested.
