Overview
The ERICHSEN 234 R/IV Wet Film Wheel is a portable, easy-to-use mechanical measuring instrument that can be used by non-technical personnel. It is rugged in construction and can be read at a glance. It is made of hard, accurately ground stainless steel. The measurement disc is 50mm in diameter and 11mm thick. It includes free-swirl/spin rollers in aluminium. 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. measurement disc diameter 50mm, thickness 11mm
6. Equipped with aluminum free swirl/spin roller
7. The reading scale is engraved on the side of the disc, and each Wet Film Wheel comes with a box
8. Available in 8 different models and Measurement ranges
Principle
The wheel-shaped measuring instrument rolls on the wet-film surface, with two knurled centering rims rolling across the substrate. When the distance from the rim to the cam is equal to the measured wet film thickness, the eccentric cam adheres to the coating to achieve thickness measurement.
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
Two measurements (forward and reverse) are required to verify the results
• Observe where the wet-film mark appears when reading
• Need to compare with the opposite side to find the average value
