- This instrument has been deisgned to use the refractive index method for measuring total protein in serum.
- The protein scale has been prepared after extensive clinical analyses under taken by Dr. matsumura, Professor of Bio chemistry at the Tokyo Women's Medical College.
- His scale is based on the results obtaines form over 1400 cases.
- The scale is the most reliable one at present available. As the same as serum protein, there is a correlation between refractive index by a refractometer and urine specific gravity by a hydrometer. Urine specific gravity can be taken from refractive index. Measurement range of this unit is 1.000 to 1.050.
