HORIBA ScientificFOLLETOS-HORIBA
LAQUA DS-72 Cond/Res/Sal/TDS Color Touch Screen LCD Meter
The LAQUA DS-72 covers conductivity, resistivity, salinity, total dissolved solids (TDS) and temperature, and meets the industrial and pharmacopeia standards JIS, USP, EP, JP and CP.
A built-in auto diagnostic function lets users confirm that the instrument keeps delivering high performance and reliable readings. The meter is fully GLP/GMP compliant and can drive an external printer; for traceability, every result is stored with the sample name, user ID and calibration information. HORIBA also supplies a comprehensive range of conductivity electrodes for every type of application and sample, known for their stability and long service life.
