Coating thickness gauges can generally measure how thick a coating is
The maximum range of imported coating thickness gauge can reach 120mm
When choosing a coating thickness gauge, the larger the measuring range, the better. The larger the measuring range, the larger the probe and the lower the accuracy.
The common coating thickness gauge range is 0-1250 μm, and the PD-CT2 high-precision coating thickness gauge is 0-1500 μm, with an error of up to 1%.
If it is a coating measurement, you need to choose a special coating thickness gauge to measure the coating. You cannot use a paint film thickness gauge.
Standard test pieces of corresponding thickness are also required.
Thickness gauge calibration tips
1. Use a ladder test block to calibrate when the thickness is close to the maximum value and minimum value of the thickness to be measured (or 1/2 of the maximum value of the thickness to be measured);
2. Place the probe on a thicker test block and adjust the "Sound Velocity Correction" knob so that the thickness gauge displays a reading close to the known value;
3. Place the probe on a thin test block and adjust the "zero correction" knob to make the thickness gauge display reading close to the known value;
4. Adjust repeatedly to obtain correct readings at both the high and low ends of the measuring range, and the instrument is now debugged;
5. If the sound speed of the material is known, the sound speed value can be adjusted in advance, and then on the test block attached to the instrument, adjust the "zero calibration" knob so that the instrument displays the thickness of the test block, and the instrument is debugged.
