Germany Erichsen 234 R/I wet-film thickness measuring wheel WFT measurement Thickness Wheel

234 R/I

Wet-film thickness measuring wheel

Wet-film range 0~25μm, Graduation 1μm; in line with ASTMD standards, the material is stainless steel; Glass, wood, metal or plastic substrates can be used.

Advantages of erichsen234 wet film thickness measuring wheel:

It is portable, easy to operate and can be used by non-technical personnel. The construction is sturdy and the readings are clear at a glance. 

Measurements can be taken on any surface. Since it is all mechanical, it can be applied to glass, wood, metal or plastic substrates. 

Compared with other types of Thickness Gauges, mechanical Thickness Gauges have a better price.

Test principle:

A dish-shaped measuring instrument rolls over the surface of the wet film. During this process, two knurled, centered 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 paint.

Design and functionality:

The hardened, precisely ground stainless steel measuring disk has a diameter of 50 mm and a thickness of 11 mm. It contains an aluminum free-spinning roller that allows the instrument to roll over surfaces. 

There are 8 different models and measuring ranges (see ordering information). 

The reading scale is engraved on the side of the plate, and each instrument comes with a box.

erichsen234 wet film thickness measuring wheel test method:

Measure 1 

Pinch the guide roller of the instrument with your thumb and index finger, and place the instrument on the test surface so that the contact point is opposite to the zero line. Press the roll gently to roll the instrument toward the zero line, and then lift it up.

Measurement 2 (verification)

The instrument is placed as in position 1, but rotated in the opposite direction until it reaches the zero line.

The wet film thickness is read where the wet film mark appears, and compared with the opposite side to find the average value.
