Features

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.
