BM - B reflex blackness instrument is a kind of high sensitive reflectivity measuring instrument, for measuring the blackness degree of black object or dark grey object. The measure precision of the instrument have good correlation to the Densichon type reflex photometer of American Society for Testing Material standard (ASTM) standard. The circuit of the instrument is high precision, low drift integrated operational amplifier and large scale integrated a/d converter, so instrument readings is stable, reliable work, convenient to use.
It is mainly used for:
Ink coating, carbon black and measuring color intensity and blackness level of carbon in the rubber industry.
Features:
1. Small size, light weight, truly portable machine.
2. Power saving, worry saving, efficient, a battery can last nearly 60 hours measuring nearly ten thousand data.
3. High stability.
4. Quartz standard edition, the annual rate of change is very low.
5. Long service life LED.
6. The automatic shutdown, save power, avoid battery flow fluid cause a malfunction.
7. Optional powder-like box and press the powder injector accurate measurements.
8. Standard gray scale value transfer standard, accurate and reliable.
