Horiba LAQUA DS-72 Benchtop pH/ORP/Temp/ION Meter

Product Description

Horiba LAQUA DS-72 Benchtop pH/ORP/Temp/ION Meter

Stress-free measurement, high-end model
Water quality analysis is repeatedly performed in laboratories on a daily basis. Our high-end benchtop model was developed to provide simplicity with excellent on-site usability – from operation and maintenance through to troubleshooting.



LAQUA DS-72 meter measures conductivity, resistivity, salinity, total dissolved solids (TDS) and temperature parameters and complies with industrial pharmacopoeia standards (JIS, USP, EP, JP and CP).

The meters’ auto diagnostic function allows the user to make sure that the instruments will always give high performance and reliable measurements. Fully GLP/GMP compliant, the LAQUA can be connected to an external printer. To ensure traceability, all results are recorded together with sample name, user ID and calibration information.

We offer a comprehensive range of conductivity electrodes adapted to all type of application and sample. Recognised for their stability and longevity, HORIBA’s electrodes provide accurate measurement in all conditions.

LAQUA’s large capacitance touch screen panel : 

  • The display is easy to understand and functions menu is shown
  • Switch between digital real time graphs or analogue displays during measurement with just flick of a finger
  • Full on-screen support on the meter via an electronic user guide with colour pictures that can be called-up at any time, a problem-solving guide for calibration and measurement
