HORIBA COMPACT WATER QUALITY METERS, LACQUA TWIN, MODEL B-731

HORIBA COMPACT WATER QUALITY METERS, LACQUA TWIN,  MODEL B-731

� Only compact meter for a quick measurement sodium ion to calculate into NaCl based salt concentration unlike the conductivity converted meters.
� Flat sensor technology realizes a reliable and direct measurement of a drop of the
sample from 0.3 mL
� IP67 waterproof and dustproof
� Temperature compensation/Auto hold/Auto range change
� Special application packages for crop and soil
