HORIBA LAQUAtwin NO3-11C/NO3-11S/NO3-11 Pocket Nitrate Ion Meters

HORIBA LAQUAtwin NO3-11 Series – Portable Nitrate Ion Meter for Soil & Water Testing

The HORIBA LAQUAtwin NO3-11 Series is the only pocket-sized nitrate meter that directly measures nitrate ion (NO₃⁻) and nitrate-nitrogen (NO₃-N) concentrations from just 0.3 mL of sample (or 0.05 mL with sampling sheet B). This compact, waterproof meter is ideal for agriculture, soil analysis, water quality monitoring, and food safety testing.

Key Features:

• Ultra-Low Sample Volume: Requires only 0.3 mL (or 0.05 mL with a sampling sheet).
• Measurement Range:
  • Nitrate (NO₃⁻): 6 to 9900 ppm (mg/L)
  • Nitrate-Nitrogen (NO₃-N): 1.4 to 2200 ppm (mg/L) or 0.7 to 1100 kg/10a
• Resolution:
  • 6 to 99 ppm: 1 ppm
  • 100 to 990 ppm: 10 ppm
  • 1000 to 9900 ppm: 100 ppm
• Calibration: Up to 2 points, with auto standard recognition.
• Multiplication Compensation: Adjustable from 0.01 to 9.90.
• Temperature Display & Calibration: 0 to 50.0°C measurement, 5 to 40.0°C calibration.
• Auto Hold & Auto Stable Measurement: Ensures precise, stable readings.
• Waterproof & Dustproof: IP67-rated, ideal for field and lab use.
• Replaceable Sensor: Cost-effective for long-term usability.
• Backlit LCD Display: Clear, high-contrast screen for all lighting conditions.
• Long Battery Life: Up to 400 hours of continuous operation.
• Compact & Lightweight: 164 x 29 x 20 mm, weighing 55g (including sensor & batteries).

Model Variants:

• NO3-11C – Optimized for crop nutrient analysis.
• NO3-11S – Designed for soil solution testing.
• NO3-11 – General use for water and environmental monitoring.

Applications:

• Agriculture & Soil Testing: Measures nitrate levels in soil and plant sap to optimize fertilization.
• Environmental Monitoring: Assesses nitrate pollution in water sources.
• Food Safety & Quality Control: Ensures nitrate content compliance in vegetables and processed foods.
• Industrial & Laboratory Use: Provides quick nitrate measurements in various liquid samples.

Simply place a few drops of sample onto the flat sensor for instant nitrate readings. The auto calibration, temperature compensation, and compact design make the LAQUAtwin NO3-11 Series perfect for on-the-go nitrate analysis.
