Horiba LAQUAtwin NO3-11S Nitrate Ion Meter (Soil Kit)

Karya Mandiri Techindo has a wide range of Horiba products – search by type, or model, or filter by brand to find the one you are after. If you still can’t find it contact us..

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.
