B-343 Compact Nitrate Meter

Overview

The twin NO3 meter is designed for general purpose nitrate measurements, agricultural applications to measure nitrate in plant leaves, and nitrate in soil samples. Flat sensor technology enables measurements with only a few drops of sample. Measurements are simple, quick, and accurate.

Features

  • Waterproof construction.
  • Automatic calibration (selection of 1 point or 2 point calibration)
  • Wide measuring range.
  • As little as 0.3 ml (6 drops) of sample required.
  • Selectable analysis of nitrate or nitrate as nitrogen.
  • Selectable units of measure (ppm, mg/L, kg/10a)
