MN-B Reflective Blackness Meter Test for Coloring Strength and Blackness of Ink, Carbon Black, and Rubber

The MN-B reflective blackness meter is a highly sensitive reflectivity measuring instrument used to measure the degree of blackness on the surface of black and dark gray objects. The measurement accuracy of the instrument has a good correlation with the dense reflection photometer specified by the American Society for Testing and Materials (ASTM) standards. The measurement circuit of the instrument uses high-precision, low drift integrated operational amplifiers and large-scale integrated circuit A/D converters, so the instrument readings are stable, the work is reliable, and the use is convenient.

Mainly used for:

Determination of coloring strength and blackness of carbon in ink coatings, carbon black, and rubber industries.

Product Features:

1. A compact, lightweight, and truly portable device.

2. Energy saving, worry free, and efficient, one battery can be used continuously for nearly 60 hours to measure nearly 10000 data points.

3. High stability, ready to test.

4. Quartz crystal standard version with extremely low annual variation rate.

5. LED long-lasting light source.
