Features of RCTG-A Coating Thickness Gauge:
1. The integrated design allows one-handed operation, ideal for routine testing scenarios, while the external probe version accommodates measurements in confined spaces.
2. Featuring digital probe technology with drift-free zero positioning, this gauge requires no calibration - simply perform a quick zero adjustment for precise measurements.
3. The auto-recognition system instantly identifies ferrous metals, non-ferrous metals, or non-metallic substrates within 0.5 seconds, delivering rapid response measurements in just 0.5 seconds per reading.
4. Our temperature compensation technology maintains measurement accuracy across varying environmental temperatures.
5. The wear-resistant ruby probe tip ensures extended service life and consistent performance.
6. Capable of measuring coating thickness on ultra-thin substrates with high precision.

Precautions: 

1. The measurement must be performed with point contact. Sliding the probe across the test surface is strictly prohibited. 
2. During measurement, the probe must be centered over the point to be measured. The outer edge of the probe should not extend beyond the surface being measured. 
3. Conduct measurements at a distance from strong magnetic sources (such as magnets and speakers) and intense electromagnetic fields (such as transformers and induction cookers). 
4. Prior to using the instrument, it is advisable to perform a zero - setting operation. 
5. Ensure that the test surface is clean. Dust, dirt, and other contaminants on the measurement surface can affect the accuracy of the measurement results. 
6. When the instrument indicates "low battery", replace the batteries with new ones. 
7. For the RRK - B model of the coating thickness gauge, it is recommended to perform multi - point calibration before use. 
8. The instrument exhibits the best stability in the single - measurement mode. For precise measurements, the single - measurement mode is recommended. 
9. Due to factors such as surface roughness, dust, and scratches on the workpiece, the instrument may not display 0 μm when measuring the same position again after zero - setting. Correct and proficient operation of the instrument is essential; otherwise, it may lead to unstable measurement values.
