Overview
The ERICHSEN 234 R/V wet-film thickness gauge is a portable, easy-to-use mechanical thickness gauge that can be easily used by non-technical personnel. It is rugged and easy to read. It is made of hardened, accurately ground stainless steel. The measurement disc is 50mm in diameter and 11mm thick. It is equipped with an aluminum free-swirl/spin roller. It can be measured on any substrate surface such as Glass, Wood, Metal or Plastic at an affordable price.
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. Equipped with aluminum free swirl/spin roller
6. The reading scale is engraved on the side of the disc, and each Wet Film Wheel comes with a box
7. Compared with other types of thickness gauges, the price is more favorable
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 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, make the contact point opposite to the zero line, press the rolling lightly to make the instrument roll to the zero line, and then lift it up
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 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
• Lift the instrument immediately after measurement
• Readings should be taken from where the wet-film mark appears
• Need to compare with the opposite side to find the average value
