Overview
The TQC brand Wet Film Wheel VF2256 is a wet film thickness measurement tool designed according to ISO 2808-74 standards. It uses the scale rolling of the wheel-rail eccentric wheel to obtain the wet film thickness, expressed in μm. The Thickness gauge is suitable for measuring Coating wet film thickness. It can measure various Coatings such as Paints and varnish. It can not only measure on flat substrates, but also perform High Accuracy measurement on curved substrates.
Features
1. Designed and produced according to ISO 2808-74 standards, there are nicks on the outer wheel, the outer edge can better fit the baseplate, grasp the surface of the measurement substrate and prevent slippage
2. Suitable for measuring the wet film thickness of Coatings, Paints, varnishes, etc
3. Coating wet film thickness meter is made of stainless steel, handheld part of aluminum
4. Equipped with precision roller bearings
Principle
The Wet Film Wheel measures wet film thickness by scaling the wheel-rail eccentric wheel. During measurement, the wheel rolls over the wet-film and touches the substrate, and the reading at the end of the wet part of the center wheel is the wet film thickness, expressed in μm.
Applications
Coating, Paints, varnish wet film thickness measurement
Steps
1. Grip the center axis of the wet film thickness measurement wheel, starting from the maximum film thickness scale value, reducing the risk of inaccurate measurement due to surface tension
2, let the wheel roll through the wet-film, the wheel to touch the substrate, the wet film thickness measurement wheel forward and backward each rolling at least one rings, the rolling process should be slow enough to make the wheel in full contact with the coating, the center wheel wet part The end reading is the wet film thickness
3. Use a wet film thickness measurement wheel on the pipeline to measure the pipeline of the entire longitudinal axis
4, for the hard plane, the peak value of the measurement surface, indicating the minimum wet film thickness
Notice
• Coating on the test plate, the thickness of the wet paint film should be measured as soon as possible to reduce the thinning of the paint film caused by solvent volatilization
• The wet film thickness measurement wheel uses a robust design and is a precision tool. Do not drop or knock the wet film thickness measurement wheel
• After use, the wet film thickness measurement wheel should be cleaned immediately
• Use a soft rag to clean the wet film thickness measurement wheel, do not use Machinery cleaning, such as wire brush or sandpaper, in addition, the use of corrosion cleaners may cause long-term damage to the wet film thickness measurement wheel
• The wet film thickness measurement wheel should be placed in the box when not in use
