Overview
The ERICHSEN 234 R/II wet film thickness gauge is a portable, easy-to-use mechanical measuring instrument that can also be used by non-technical personnel. It is rugged and can be read at a glance. It can be measured on any substrate surface such as Glass, Wood, Metal or Plastic, and is more affordable than other types of thickness gauges.
Features
1. Portable design, easy to operate, can also be used by non-technical personnel
2. Sturdy structure, clear readings at a glance
3. Mechanical measurement, can be carried out on any surface
4. Adopt hardened and accurately ground stainless steel material
5. measurement disc diameter 50mm, thickness 11mm
6. Includes aluminum free swirl/spin rollers
7. The reading scale is engraved on one side of the disc
8. Each Wet Film Wheel comes with a box
9. Price concessions
Principle
The wheel-shaped measuring instrument rolls on the wet-film surface, and the two knurled centering rims roll over the substrate. When the distance from the rim to the cam is equal to the measured wet film thickness, the eccentric cam will stick to the coating.
Applications
Glass, wood, metal, plastic substrates
Standards
ASTM D 1212、EN ISO 2808
Steps
1. Pinch the guide roller of the instrument with the thumb and index finger, place the instrument on the test surface, so that the contact point is opposite to the zero line. Press lightly to roll, so that the instrument rolls to the zero line, and then lift it.
2. Place the instrument in a position such as 1, but swirl/spin in the opposite direction until it reaches the zero line.
3. The wet film thickness is read out at the place where the wet-film mark appears, and compared with the opposite side to obtain the average value.
Notice
• Light pressure rolling instrument is required for measurement
• The instrument needs to be lifted after measurement
Two measurements are required to verify the results
• The reading needs to be averaged against the opposite side
