Overview
The QILI MN-R reflectance is an ultra-small Portable instrument for measuring the hiding power of Paints, varnish-light Paints, colorants, pigments, and various colorants on substrates.
Features
1. Ultra-small design, easy to carry and on-site measurement, is currently the smaller and lighter weight reflectance instrument in China.
2. No need for zero point calibrating, simple operation.
3. Super power saving design, using a AA battery (rechargeable battery or alkaline battery can be used), can be used continuously for more than 50 hours, about 10,000 data measurement.
4. Special moisture-proof process, can be used in various harsh environments.
5. Long life Illuminant, no need to replace.
6. Standard values transmitted by the national calibration whiteboard are accurate and reliable.
Principle
The instrument uses 45/0 ° irradiation conditions to evaluate hiding power by measurement of sample reflectance without zero point calibrating.
Applications
Paints, varnishes - Paints, colorants, pigments, colorants - Determination of hiding power of substrates
Standards
ISO3906-1980（E）、GB/T13452.3-92、GB9270-88、GB5211.17-88
Steps
1. Install a AA battery (rechargeable battery or alkaline battery).
2. Align the instrument to the tested sample for measurement.
3. Read the measurement results of the indication interval 0~ 100.
Notice
• Permissible Ambient Temperature is 0~ 40 ℃.
• Allowable relative humidity does not exceed 85%.
Make sure the battery voltage is within the range of 0.8V to 1.5V before use.
• The measurement aperture is 12 * 17mm elliptical, and the sample needs to be aligned.
