From "manual analysis" to "semi-automation"

A variety of functions, such as an easy-to-read color touch panel and one-handed precision dispensing, support manual titration.

How to use:

(1) Check the settings

(2) Titrate by one of the following methods

(3) Results Display


 Titration Support


  • Recalculate concentration (last result only)
  • Shorten time by setting continuous dripping
  • Stores up to 99 points of titration volume
  • Three types of titration patterns


【 Concentration Formula 】


Arbitrary formulas can be created by combining the following

D: Titration volume (mL)

B: Blank (mL)

M: Titrant concentration

F: Factor( potency )

S: Sample size

K: Coefficient

Dispensing Support



  • Can dispense a set volume
  • Setting of dispensing operation interval time
  • Set the number of repetitive operations
  • Totalize/non-totalize dispensing

Extended Functions


  • Host/balance connection via RS-232C
  • Can also be used as a Buret for Auto Titrator *For COM-A19/1700(A)*Signal code (P/N: HSJ832875) is required.
  • Optional magnetic stirrer
  • Easy replacement of Buret Head  *Conventional H-1700 can also be used.
