Overview
The ERICHSEN 234 R/VIII 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 is equipped with an aluminum free-swirl/spin roller for measurement on any surface such as Glass, Wood, Metal or Plastic substrates at an affordable price.
Features
1. Portable, easy to operate, and can be used by non-technical personnel.
2. The structure is sturdy and the readings are clear at a glance.
3. Mechanical design, can be measured on any surface.
4. Adopt hardened, accurately ground stainless steel material, measurement disc diameter 50mm, thickness 11mm.
5. Contains aluminum free swirl/spin rollers for easy rolling on the surface.
6. The reading scale is engraved on one side of the disc, and each Wet Film Wheel comes with a box.
7. There are 8 different models and Measurement ranges, with good prices.
Principle
The wheel-shaped measuring instrument rolls on the wet-film surface, and the two knurled pairs of 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, thereby achieving 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, make the contact point opposite to the zero line, and press the rolling 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 at the place where the wet-film mark appears, and compared with the opposite side to obtain the average value.
Notice
• Press the roll lightly during the measurement process to avoid excessive force.
• Ensure that the contact point of the instrument is properly aligned with the zero line when rolling.
• When reading the wet-film mark, compare it with the opposite side to obtain an accurate average value.
