German Yilixin PIG455 paint film thickness gauge

ErichsenPIG455paint film thickness gaugeTest Principle：
The 455 measurement is based on a standard wedge cutting procedure: the coating is cut to the substrate at a defined angle, and the thickness (s) of the coating is calculated based on the triangular projection (b) of the cutting surface, which is determined by a microscope and cutting angle (a). According to the same principle, the thickness of each layer of the multi-layer coating system can also be calculated. For adhesion testing that complies with AS 1580 Meth 408.1 standard, the width of the rolled up area of the coating during cutting operation is related to the projection b.

Erichsen518S paint film detector

erichsen518SPaint film detectorTesting principle:
The 518S thickness gauge measures by using the standard wedge cutting method. In this case, the sample is cut at a specified angle. The thickness of the coating can be calculated using simple geometric relationships by projecting the width of the cutting surface. 518S controls the damage of the coating to a very small conical hole as shown in the figure. In a measuring microscope, a series of concentric circles can be seen. By measuring the radius difference of the concentric circles with a measuring microscope and multiplying it by a known coefficient, the film thickness can be calculated.
erichsen518SPaint film detectorIntroduction:
The 518S paint film inspection instrument is a compact device. All important components, including drilling tools, measuring microscopes, sample lighting, and batteries, are installed in a sturdy casing. The drill bit and microscope can slide horizontally, giving the 518S a unique feature: the instrument can measure without moving after drilling. The drill bit is elastically installed in the groove, so that it can be pressed onto the sample with the least force, and then the drill bit will automatically start. Tungsten carbide drill bits are easy to replace and can provide high-precision drill bits with different cutting angles to meet four standard measurement ranges. The measuring microscope has a magnification of 50 and 100 scale lines, so the resolution is 1% regardless of the range.
The lighting switch is located in front of the 518S paint film inspection instrument and can be set to continuous or intermittent lighting to extend battery life. It uses a 9V rechargeable battery and can also be operated using a charger.
The microscope can move in two directions (rotate 90 °) and the scale can be rotated, so the 518-S is particularly suitable for measuring elliptical holes in curved samples.
Operation Method:
Using 518SPaint film inspection instrumentMeasuring coating thickness is very simple: make a comparative mark with a marker pen, place the instrument on the surface of the sample, move the drill bit above the testing point and lower it to turn on the motor. Drill through the coating until it reaches the substrate. Move the microscope to the top of the hole, turn on the light, read the scale number between the substrate and the comparison mark, and multiply it by a scale factor to obtain the measurement
result. For special applications (single coating of multi-layer coating systems, measurement of curved samples), please refer to the operating instructions.

Erichsen234 wet film thickness measuring wheel

erichsen234Wet film thickness measuring wheeladvantage:
Portable, easy to operate, and can also be used by non-technical personnel. The structure is sturdy and the reading is clear at a glance.
Measurement can be performed on any surface. Because it is entirely mechanical, it can be applied to glass, wood, metal, or plastic substrates.
Compared with other types of thickness gauges, mechanical thickness gauges have a better price
Test Principle：
The disc-shaped measuring instrument rolls on the wet film surface. During this process, two rollers roll over the substrate with the center wheel rim. When the distance between the wheel rim and the cam is equal to the measured wet film thickness, the eccentric cam will stick to the coating.
Design and functionality：
The diameter of the hardened and precisely ground stainless steel measuring disc is 50 mm and the thickness is 11 mm. It contains an aluminum freely rotating roller that allows the instrument to roll on the surface.
There are a total of 8 different models and measurement ranges (see ordering information).
The reading scale is engraved on one side of the disc, and each instrument comes with a box.
erichsen234Wet film thickness measurement wheel testing method:
Measurement 1
Pinch the guiding roller of the instrument with your thumb and index finger, and place the instrument on the testing surface so that the contact point is opposite to the zero line. Gently press and roll the instrument towards the zero line, then lift it up.
Measurement 2 (Verification)
The instrument is placed in position 1, but rotated in the opposite direction until it reaches the zero line.
The wet film thickness is read at the location where the wet film mark appears, and compared with the opposite side to obtain the average value.

Test PrincipleThe height difference between the upper surface of the wet coating and the substrate (D) is measured by manually adjusting the plug (1) (with 2 legs (2)) of the instrument to penetrate the coating and stay on the substrate.

test method：
1Dry film measurement：
1) Setting up
Remove the protective cover and place the instrument vertically on the flat surface of the glass plate. If the pointer reading is not zero, it can be adjusted through the slot in the protective cover until the pointer reaches zero position,.
2) Preparation of measurement points
At the measurement point, the coating needs to be carefully scraped open in a 3mm area until it reaches the substrate.
3) Measurement
Place the instrument on the measurement area so that the pins are in contact with the exposed substrate, and the dry film thickness can be directly read in micrometers.
If it is a soft coating, a razor can be placed under the foot of the support.
IIWet film measurement：
First, lift the pin with a rolling screw to obtain a reading that is 0.5 μ m higher than the support pin. Then place the instrument on the wet film, with the legs resting on the substrate. Slowly lower the pin using a rolling screw until it reaches the wet film. The thickness of the coating can be directly read from the dial, in micrometers.
