Overview
The MN-W Handheld whiteness meter is a Portable device specially developed by QILI brand for easy portability and on-site measurement. It is as accurate as the data of traditional Benchtop models. The instrument is designed in full accordance with the Standard light source and Illumination conditions stipulated by the International Commission on Illumination (CIE). Through strict testing and debugging, it is suitable for many national standards and conforms to national Measurement and Appraisal Procedures.
Features
1. Small size, light weight, real laptop.
2. The Illuminant correction system created in China has effectively changed the market situation that Portable whiteness meters cannot measure fluorescent whiteness, which is completely comparable to Benchtop machines.
3. No need for zero point calibrating, simple operation.
4. Power saving, worry-free and effective, a new battery can be used continuously for more than 60 hours, and about 10,000 data can be measured.
5. The special moisture-proof process allows you to use it with confidence in various harsh environments.
6. Automatic shutdown saves power and avoids battery failure due to liquid flow.
Principle
The instrument adopts 45/0 illumination conditions and uses D65 Illuminant and R457 blue light whiteness formulas for measurement to ensure accurate and reliable data.
Applications
Spinning & weaving printing and dyeing, paints Coating, chemical building materials, paper Cardboard, plastic products, white cement, ceramics, enamel, porcelain clay, powder tale, starch, flour, salt, detergent, cosmetics and other objects whiteness measurement.
Standards
GB2913, GB5950, GB8940.1, GB12097, GB13025.2, National Measurement and Appraisal Regulations JJG512-2002
Steps
1. Turn on the instrument power.
2. Align the measurement aperture to the object to be measured.
3. Perform measurement, the instrument automatically displays the whiteness value.
4. Automatic shutdown after use to save power.
Notice
• Make sure the battery is fully charged and avoid using it under low power.
When used in harsh environments, pay attention to moisture protection.
• Avoid battery flow and check battery status regularly.
• Keep the instrument stable during measurement to obtain accurate data.
