Overview
JFB-I Portable reflectivity meter is a special instrument developed by PUSHEN brand for the implementation of international standards and national standards in the chemical industry such as paints, pigments, inks, etc. It can be used for the determination of paint film hiding power. The instrument is suitable for the determination of white and light Paints hiding power, and is also often used for the comparison test of paints and Paints.
Features
1. Fully comply with international standards and national standards
2. Designed for paint, pigment, inks industry
3. Portable design, easy to use on site
4. High Accuracy measurement, resolution up to 0.1
5. Repeatability is good, Repeatability ≤ 0.3
6. Indication Error is small, only +/- 1.0
Principle
The instrument is composed of a host, a standard board (one black and white), a charger, etc., and adopts the principle of 0 ° irradiation and diffuse reflection reception. When the reflected light of the sample acts on the surface of the Photocell, photovoltaic cell, an electrical signal is generated and input to the DC amplifier for amplification, and the reading is displayed. The indication of the instrument is proportional to the light intensity of the reflection on the measured surface.
Applications
Paints, pigments, inks
Standards
GB/T 13452 3、5211 17、23981、9270、ISO 2814、3905、3906
Notice
• Please read the instructions carefully before use
• Keep the standard board clean and avoid scratches
• Measurement accuracy by calibrating instruments regularly
• Avoid use in a strong light environment
• Keep the charger and accessories properly
