Overview
C84-III 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 coatings, pigments, inks, etc., which can be used for the determination of paint film hiding power.
Features
1. Fully comply with international standards ISO3906-1980 (E), national standards GB/T13452.3-92, GB9270-88, GB5211.17-88 requirements
2. High resolution 0.1, Repeatability ≤ 0.3, Indication Error +/- 1.0
3. Portable design, shipment size 210x240x100mm, weight only 4kg
Principle
The instrument is composed of Probe, host, standard board (one black and white), working ceramic board (two black and white), etc. Probe uses 0 ° irradiation, diffuse reflection reception principle, when the reflected light of the sample acts on the surface of the silicon Photocell, photovoltaic cell, an electrical signal is generated and input to the DC amplifier for amplification, and readings are displayed.
Applications
Paints, pigments, inks
Standards
ISO3906-1980(E)、GB/T13452.3-92、GB9270-88、GB5211.17-88
Steps
1. Connect the power supply (220V AC 50Hz)
2. Use standard plates to calibrate
3. Align Probe to Specimen Surface
4. Read the reflectance value on the display (0~ 100 range)
Notice
• Power supply voltage 220V AC 50Hz
• Use a standard plate calibrating instrument before use
• Keep Probes and Specimen Surfaces Clean
• Avoid use in strong light interference environment
• Instrument indication interval 0~ 100, resolution 0.1, pay attention to reading accuracy
