Original price $360.00
Current price $299.99

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.
