Overview
ERICHSEN 234 R/I wet-film thickness wheel is a Portable mechanical measuring instrument, made of stainless steel, with a measurement disc diameter of 50mm and a thickness of 11mm. The instrument has a robust design, clear and intuitive readings, simple operation and can be used without professional skills. It is suitable for wet film thickness measurement on a variety of substrate surfaces.
Features
1. Portable design, easy to operate, can also be used by non-technical personnel
2. The structure is sturdy and durable, and the readings are clear at a glance
3. Perform measurements on any surface, including Glass, Wood, Metal or Plastic substrates
4. Mechanical design offers a better price advantage than Miscellaneous type thickness gauges
5. 8 Different Models and Measurement ranges
Principle
The disc 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 the Coating, and the thickness value will be read by observing the adhesion position of the Coating.
Applications
Glass, wood, metal, plastic and other substrate surface wet film thickness measurement
Standards
ASTM D 1212、EN ISO 2808
Steps
1. Pinch the guide roller of the instrument with the thumb and index finger, and place the instrument on the test surface so that the contact point is opposite to the zero line
2. Press lightly to roll, so that the instrument rolls to the zero line, and then lift it up.
3. Place the instrument in the position as in step 1, but swirl/spin in the opposite direction until it reaches the zero line
4. 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
• Validation measurement is required after measurement
• The reading needs to be compared with the opposite side and averaged
• Verify that the instrument model matches the Measurement range before use
