Concentration Meter

High accuracy high performance type Ace II

  • Overview
  • Specifications


Allows highly accurate measurement.
An inline type system allowing simultaneous measurement of up to 4 components

List of chemical solutions by device type


Achieves the world’s highest accuracy

By adjusting the temperature of the measurement cell and optical filter, the impact on measurement results caused by temperature changes is minimized.

Automatic measurement and pure water calibration

Reduces the stress of measurement and maintenance by incorporating a solenoid valve.

High performance data processing

Allows simultaneous measurement of up to 4 components. Multi calibration curves are available.
