One. summary.
The HY-BDY digital whiteness meter is mainly suitable for measuring the whiteness of objects or powders with flat dry and non colored surfaces. It is possible to accurately obtain a whiteness value that is consistent with visual acuity. For materials treated with fluorescent whitening agents, the whiteness value after fluorescent whitening can be quantitatively reflected.
The opacity of paper can be accurately measured.
2、 Technical parameters:
1. Measurement range: 0-199.9%
2. Display mode: digital display
3. Fenyi rate: 0.1
4. Measurement aperture: φ30mm
5. Testing conditions: 45/0
6. Measurement method: R457 blue light whiteness
7. Instrument light source: 12V/35W halogen turbulence lamp
8. Zero drift: ≤ zero point two
9. Indication drift: ≤ zero point three
10. Voltage fluctuation and stability: ≤ zero point three
11. Lateral repeatability: ± 20%
