LAQUAtwin NO3-11C/NO3-11S/NO3-11 – Horiba Pocket Water Quality Meters

Your lab-in-a-pocket
HORIBA’s unique compact meter integrates the electrode, display and sample container to enable simple, effective on-site testing by direct measurement from a single drop.

LAQUAtwin NO3-11C/NO3-11S/NO3-11 – 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.
