1.1.4 Measurement Principle
This instrument measures the oral rinse measurement sample using the dual-
wavelength reflectance method. The change in the color of the test strip after
sample application is measured by the reflectance of light with wavelengths of 565
nm, 635 nm and 760 nm. Then, results are obtained for cariogenic bacteria,
acidity, buffer capacity, blood, leukocyte, protein and ammonia.
