Overview
The QILI MN-BII wet/dry dual-use blackness meter is an ultra-small portable measuring instrument with 45/0 illumination conditions and a CIE-specified D65 light source for rapid on-site measurement.
Features
1. Ultra-small design, easy to carry and on-site measurement, is the smaller and lighter weight blackness meter in China
2. No need for zero point calibrating, simple operation
3. Super power saving design, using a AA battery can be used continuously for more than 50 hours, about 10,000 data measurements
4. Special moisture-proof process to adapt to various harsh environments
5. Long-life light source, no need to replace
6. Backlit display for easy operation under various conditions
7. Accurate power display to ensure accurate measurement
8. Digital encoder adjustment, wide adjustment range, long service life
Principle
The instrument adopts 45/0 illumination conditions (45 degree emission, 0 degree reception), uses D65 light source illumination in line with CIE regulations, and detects the blackness value of the sample through Optical inspection Measurement principle, with automatic zero stabilization function.
Applications
Field measurement, industrial testing, quality control
Steps
1. Install a AA battery
2. It can be used when turned on, no need for zero point calibrating
3. Align the instrument measurement hole with the tested sample
4. Read the measurement values on the display
