HORIBA LAQUAtwin K-11 Potassium Ion Pocket Water Quality Meter

HORIBA LAQUAtwin K-11 Portable Potassium Ion Meter for Soil, Food & Water Testing

The HORIBA LAQUAtwin K-11 is a portable, waterproof potassium ion meter, designed for fast and precise potassium (K⁺) concentration measurements in soil, plant sap, water, and food samples. Using ion-selective electrode (ISE) technology, it enables direct measurement from just 0.3 mL of sample (or 0.05 mL with a sampling sheet), making it ideal for agriculture, environmental monitoring, food quality control, and clinical research.

Key Features:

• Ultra-Low Sample Volume: Measures potassium levels with just 0.3 mL (or 0.05 mL with a sampling sheet).
• Wide Measurement Range: 4 to 9900 ppm (mg/L) or 0.1 to 250 mmol/L.
• High-Resolution Readings:
  • 0 to 99 ppm: 1 ppm
  • 100 to 990 ppm: 10 ppm
  • 1000 to 9900 ppm: 100 ppm
• Calibration: Up to 2 points, with standard recognition at 150 & 2000 ppm K⁺.
• 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, designed for field and laboratory use.
• Replaceable Sensor: Cost-effective for long-term usability.
• Backlit LCD Display: Clear readings in all lighting conditions.
• Battery Life: Up to 400 hours of continuous operation.
• Compact & Lightweight: 164 x 29 x 20 mm, weighing 55g (with sensor & batteries).

Applications:

• Agriculture & Soil Testing: Determines potassium levels in soil solution, plant sap, and hydroponics.
• Food & Beverage Industry: Measures potassium concentration in fruits, vegetables, and processed foods.
• Environmental Monitoring: Tests potassium levels in freshwater, seawater, and wastewater.
• Clinical & Sports Science: Assesses potassium levels in sweat for hydration and health monitoring.

Simply place a few drops of sample onto the flat sensor for instant potassium readings. With automatic calibration, temperature compensation, and a rugged, waterproof design, the LAQUAtwin K-11 is the perfect tool for quick and reliable potassium testing.
