Overview
QYG type film Freshness tester is HuiNuo brand newly developed small portable computer, technical parameters fully comply with the national standard GB9754 and international standard ISO2813, all performance indicators meet the requirements of the national Measurement verification regulations JJG696-2002 first-class work machine. This product is suitable for paints, coatings, inks, Stone, paper, enamel, ceramic tile and other flat products Glossiness measurement, is a satisfactory instrument for measuring film decoration performance, can grade film especially the film on the surface of cars, simple and intuitive measurement of distinctness of image grade data.
Features
1. Portable design.
The technical parameters comply with the national standard GB9754 and the international standard ISO2813.
3. The performance indicators meet the requirements of the national Measurement verification regulations JJG696-2002.
4, photoelectric combination, through the naked eye observation can read the distinctness of image level DOI value, the operation is intuitive and simple.
5, suitable for a variety of flat products gloss measurement.
Principle
The QYG type film fresh projection instrument is a photoelectric combined Portable instrument. Its principle is to map the digital on the digital plate through the illumination of light and the reflection of the measured surface in the observation hole. Through the naked eye observation of the measurement person, the DOI value of the read distinctness of image level achieves the purpose of measurement film surface decoration performance index. The higher the DOI value, the better the distinctness of image. The instrument is composed of a shell, an imagery room, an optical path, an eyepiece and a panel.
Applications
Glossiness measurement of paints, paints, inks, Stone, paper, enamel, ceramic tile and other flat products, car surface film grading
Standards
GB9754、ISO2813、JJG696-2002
Steps
1. Open the cover and install the battery or plug in the external power supply.
2. Press the power switch, observe the voltmeter, and turn the voltage adjustment knob to keep the pointer in the 4.4V position and the luminance meets the requirements. If the pointer cannot be adjusted to 4.4V after using a dry battery, the battery should be replaced.
3. Put the standard reflection board on the table, align the measurement window at the bottom of the instrument with the standard reflection board, then press the power switch, observe the digital board reflected on the standard reflection board from the eyepiece, and confirm that the digital board can be clearly read. The number with DOI value of 1.0 on the digital board.
4. Place the instrument on the surface of the object to be measured, make the measurement window and the measured face good, press the power switch, observe the mapped numbers from the eyepiece barrel, and read the DOI value numbers that can be clearly seen.
5, the sex repeability measurement 5 times the average value as a result.
Notice
• The determiner should be someone who can clearly read the DOI value of 1.0 on the reflection plate.
• If the pointer cannot be adjusted to 4.4V after adjusting with a dry battery, the battery should be replaced.
