Accurate measurement from only a single drop of sample onto HORIBA's original flat sensor. LAQUAtwin product line-up offers easy, quick, and reliable measurement of 8 parameters. It brings new dimension to your water quality testing.

LAQUAtwin NO3-11C/NO3-11S/NO3-11

Overview

 Temperture  
Water proof Micro Volume  2-point calibration   

Features

The only pocket meter that directly measures nitrate ion and nirate-nitrogen concentrations in 0.3ml sample (or 0.05ml sample with sampling sheet B). Unique sensor allows measurement of viscous liquids, solids, and even powder samples. No need for a beaker to calibrate your meter or measure a sample. Just place few drops of the standard or sample onto the flat sensor. This procedure saves you time and prevents wasting your precious sample.
