Overview

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.

Two types of solutions – distilled water as the standard solution and the sample liquid to be measured – are injected into the instrument with syringes.

 

Output is RS-232C.

 

Optional printer DP-AP is availaable.


By using a standard solution other than distilled water, solutions of higher concentration can also be measured.
