Overview
The NR4510 reflectivity meter is a Portable reflectance test instrument independently developed by 3nh brand. It is lightweight and portable, stores calibrated values at one time, and is free from frequent calibrating, which is convenient for on-site measurement. The instrument is suitable for measuring various mirror reflectance values, as well as the hiding power of Paints, varnish-shallow Paints and colorants, pigments, Glass, ceramics, and various colorants on substrates.
Features
1. Professional white standard board (national standard delivery standard), more accurate.
2. Intelligent storage of calibrated values, no need to calibrate frequently.
3. Compact and portable, one-handed operation, no need to press the button, directly measure the reflectance value.
4. Rechargeable lithium-ion battery 3.7V@3200mAh, charging once, can be used for a long time.
5. Long Life Illuminant, Stability, Fast measurement, Instant measurement.
Principle
The instrument adopts 45/0 illumination mode (45 direction incidence /0 degree reception), which conforms to CIE No. 15 and GB/T 3978. Using LED Illuminant and silicon photodiode sensor, the detector Response function is D65 Illuminant xCIE10 degree Response, which can measure reflectance and hiding ratio (contrast ratio).
Applications
Specular reflectance measurement, Paints, varnish - Paints, colorants, pigments, Glass, ceramics, various colorants - Determination of hiding power of substrates
Standards
ISO3906-1980(E)、GB/T13452.3-92、GB/T23981-09、GB9270-88、GB5211.17-88、CIE No.15、GB/T 3978
Steps
1. Use after instrument preheating correction.
2. Align the instrument to the measurement surface.
3. Direct measurement, no need to press the button to display the reflectance value.
4. Measurement time is about 1.5 seconds.
Notice
• Temperature range from 0 to 40 ° C (32 to 104 ° F).
• Storage Temperature range -20~ 50 ° C (-4~ 122 ° F).
• The measurement diameter is the platform measurement diameter of φ 20mm (the measurement diameter of φ 10mm can be customized).
• Repeatability requirements are within Delta R0.1 (after instrument preheating correction, the average value of the whiteboard is measured 30 times at intervals of 5s).
• Inter-instrument Agreement requires Delta R within 0.5 (BCRA Series II 12 color plate measurement average).
