Erichsen296 dry wet film thickness gauge features:
Both dry film thickness and wet film thickness can be measured.
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 fully mechanized, it can be applied to glass, wood, metal, or plastic substrates.
Compared with other types of thickness gauges, * * * mechanical thickness gauges have better prices.

Testing principle: The 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.

Testing method:
1、 Dry 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.
2、 Wet 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.

Measurement range~500 μ m Reading accuracy 5 μ m
