Overview
The ERICHSEN 234 R/VI wet-film thickness gauge is a portable, easy-to-use mechanical thickness gauge that can be used by non-technical personnel. Rugged and easy-to-read, the ERICHSEN 234 R/VI wet-film is made of hard, accurately ground stainless steel. The measurement disc is 50mm in diameter and 11mm thick. It is equipped with free-swirl/spin rollers in aluminium for measurement on any substrate surface, such as Glass, Wood, Metal or Plastic.
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, price concessions
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. 8 Different Models and Measurement ranges
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, 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. The instrument is placed in the same position as the first step, 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
• Two measurements are required
• The reading needs to be averaged against the opposite side
