The LAQUA DS-70 series is designed to concurrently measure Conductivity, Resistivity, Salinity, TDS, and Temperature. Specifically, the Model DS-72 adheres to the standards of various industrial pharmacopoeias (JIS, USP, EP, JP, and CP).

These meters feature an auto diagnostic function, ensuring consistent high performance and reliable measurements. Fully compliant with GLP/GMP standards, the LAQUA can be seamlessly connected to an external printer. For enhanced traceability, all results are recorded alongside sample names, user IDs, and calibration information.

Our range of conductivity electrodes caters to diverse applications and samples. Known for stability and durability, HORIBA’s electrodes deliver precise measurements under various conditions.

Key Features:

  1. LAQUA’s large capacitance touch screen panel:
    • Displays easily understandable values and function menus.
    • Enables seamless switching between digital real-time graphs and analogue displays with a simple finger gesture.
    • Offers on-screen support through an electronic user guide with color pictures, accessible at any time. It includes a problem solver guide for calibration or measurement.


  1. User-friendly navigation for main unit and electrode inspections.
  2. Comprehensive support for pharmaceutical pure water guidelines in various countries (USP/EP/JP/CP).
  3. Customizable auto-hold function for calibration and measurement.
  4. Simultaneous connection to GLP/GMP-compatible equipment and PCs.
  5. Digital memory: Records a maximum of 2,000 sets of measurement data.
  6. USB-PC communication and USB memory support.
  7. Multi-language capabilities (Japanese, English, Chinese, Korean).
  8. Complies with FDA 21 CFR Part11.
