This model measures solutions of low concentration up to 2% at an extremely high accuracy level of ±0.005%. It is recommended for such samples as unsweetened tea and surfactants.2 types of solutions – distilled water as the standard solution and the sample liquid to be measured – are injected into the instrument with syringes.By using a standard solution other than distilled water, solutions of higher concentration can also be measured.

The DP-63 is a printer for Automatic Polarimeter AP-300, AP-100,RX-i series and DD-7. It automatically prints out Angle of rotation, International sugar scale, Specific optical rotation, Concentration, Purity, Length of observation tube, Measurement temperature, Sample number Date, Month, Year and Time.

The DP-AD is a printer for Automatic Polarimeter AP-300, AP-100, RX-i series and DD-7. It automatically prints out Angle of rotation, International sugar scale, Specific optical rotation, Concentration, Purity, Length of observation tube, Measurement temperature, Sample number Date, Month, Year and Time.The DP-AD uses regular rolled plain paper (not thermal).
