Professional Coating Thickness Measurement – Reliable, Mobile, Precise
Whether for vehicle inspection, industrial quality control, electroplating or maintenance – accurate coating thickness measurement is essential for safety, product quality and cost efficiency.
The coating thickness gauges from KERN & SOHN offer a reliable, flexible and easy-to-use solution – perfectly tailored to your application.
Depending on the model – such as the KERN JCT 100 or TB 1000-0.1F – various measurement methods are available. The devices operate using magnetic induction or eddy current technology, delivering reliable results on iron, steel, aluminium or non-ferrous metals – with automatic substrate detection on FN models.
Your Advantages at a Glance
✔ High precision from 0.1 µm – ideal for thin coatings
✔ Internal or external sensors – depending on the application
✔ Compact, mobile design – quick to use and intuitive operation
✔ Statistical functions such as mean, min/max and standard deviation (depending on model)
✔ Factory or user calibration for maximum reliability
✔ Wide range of applications – from workshop to industrial production
Especially useful: Devices like the TF 1250-0.1FN or TG 1250-0.1FN can measure hard-to-reach areas – thanks to their compact design and high-quality sensors.

? Frequently Asked Questions (FAQ) – Coating Thickness Gauges
1. How do you measure paint layer thickness?
Non-destructive methods are used – for metallic substrates, magnetic induction or eddy current techniques are common. Devices like the KERN TB 1000-0.1F deliver reliable micrometer readings (µm) directly on the object.
2. What does a paint thickness gauge measure exactly?
A paint thickness gauge measures the thickness of non-conductive coatings – such as paint, varnish, plastic or powder coating – on conductive or ferromagnetic base materials. It is used for quality control, damage analysis and repainting inspection.
3. What does "FN" mean on KERN instruments?
"FN" refers to Fe/NFe – that is, ferromagnetic metals like iron and non-ferrous metals like aluminium. FN models, such as the JCT 100, automatically detect the substrate and select the appropriate measuring method.
4. How accurate are the coating thickness gauges from KERN & SOHN?
Depending on the model, readability reaches down to 0.1 µm. Even very thin coatings can be measured precisely – essential in electroplating and surface treatment. All devices offer high repeatability to meet industrial standards.
5. How can I detect a repaint with a thickness gauge?
Significantly higher paint thickness on individual vehicle panels – for example, 150 µm instead of 90 µm – may indicate a repaint. Devices like the JCT 100 reliably detect such differences – a valuable tool for experts and used car evaluators.
6. What is a normal car paint thickness?
Factory paint thickness typically ranges between 80 and 150 µm. Readings above this (e.g. 200–300 µm) often suggest repairs or repaints. A paint thickness gauge helps to determine this objectively.
7. What is the difference between internal and external sensors?
Devices with internal sensors (e.g. TF 1250-0.1FN) are compact and mobile, ideal for quick checks. External sensor models (e.g. TB 2000-0.1F) allow flexible measurements on hard-to-reach areas such as edges, inner surfaces or cavities.
8. How often should a coating thickness gauge be calibrated?
Before each measurement series – especially when substrates change – calibration using reference foils is recommended. Devices like the TE 1250-0.1F support both factory and user calibration modes.
9. How does the statistics function work on KERN models?
Models like the TG 1250-0.1FN feature integrated statistics: they automatically calculate average, standard deviation, min and max values – ideal for documented quality control and series measurements.
10. Are there models specifically for automotive use?
Yes. The JTC model is specially designed for automotive paint thickness measurement. It features ergonomic design, robust sensor technology and high precision, even with frequent vehicle inspections.
