HORIBA LAQUAtwin NO3-11S Soil Nitrate Meter

The HORIBA LAQUAtwin NO3-11S is a professional portable meter specifically designed for soil nitrate analysis. It provides fast and direct measurement of nitrate (NO₃⁻) and nitrate nitrogen (NO₃-N) using an ion-selective electrode sensor.

Its compact design allows measurements to be performed directly in the field, making it a practical tool for monitoring soil nitrogen availability and supporting fertilization and crop nutrient management decisions.

Low sample volume

The LAQUAtwin NO3-11S requires only 0.3 ml of sample for measurement. When using the B sampling sheet, the required volume can be reduced to just 0.05 ml.

Measurements are performed directly on the sensor without requiring a laboratory beaker, making the process faster and particularly convenient for field work.

Nitrate and nitrate nitrogen measurement

The NO3-11S can display results as both nitrate (NO₃⁻) and nitrate nitrogen (NO₃-N). For soil analysis, NO₃-N results can also be expressed in kg/10a.

• Nitrate (NO₃⁻): 6–9,900 ppm (mg/L).
• Nitrate nitrogen (NO₃-N): 1.4–2,200 ppm (mg/L).
• NO₃-N for soil analysis: 0.7–1,100 kg/10a.
• Accuracy: ±10% of the measured value.
• Measurement principle: ion-selective electrode (ISE).

Specifically designed for soil analysis

The HORIBA LAQUAtwin NO3-11S uses calibration standards specifically intended for soil analysis, helping users obtain results adapted to this application.

It is particularly suitable for farmers, agricultural technicians, laboratories, agronomic consultants, researchers and fertilization professionals who need to perform regular nitrate measurements.
