The Horiba K-11 Potassium Pocket Tester was designed to determine potassium in a wide variety of samples with high precision. Thanks to the ion-selective electrode and the digital LCD screen with backlight, the tester is perfect for mobile water quality and environmental analyses. The minimal sample volume of only 0.3 ml (0.05 ml with sampling sheet) ensures reliable results even with small sample sizes.

With its 2-point calibration and automatic standard recognition, the device can be flexibly adapted to different measurement conditions. The IP67 rating for dust and water protection, along with a long battery life of up to approximately 400 hours, makes the tester highly reliable for mobile use.

Technical Features for Reproducible Potassium Measurements

The potassium tester covers a wide measurement range from 4 to 9,900 ppm (mg/L) and additionally displays temperatures up to 50 °C with a resolution of 0.1 °C. The integrated temperature compensation ensures stable results even under changing environmental conditions.

Automatic standard recognition, adjustable calibration values, and multiplication compensation guarantee high reproducibility across different sample types. This makes the K-11 suitable for both routine and demanding analytical tasks.

Why Potassium Measurement Is Important – Ideal with the Horiba K-11 Hand Tester

Potassium is an essential parameter in water, environmental, agricultural, and food analysis. In water bodies, potassium content affects water quality, in soils it is a key nutrient for healthy plant growth, and in food it plays an important role for nutrition and labeling requirements.

A mobile potassium hand tester enables rapid on-site analysis without time-consuming laboratory testing. Changes can be detected immediately, and decisions can be made right away. The Horiba K-11 combines this flexibility with high measurement accuracy and ease of use – ideal for fieldwork, routine checks, and scientific studies.

Where Can It Be Used?

• Environmental Monitoring: The K-11 is a fast and precise measurement tool for environmental technicians and scientists monitoring potassium concentrations in water bodies to ensure water quality and identify contamination sources.
• Agriculture: The K-11 allows farmers and agronomists to measure potassium in soil. This is crucial for fertilizer application and improving plant growth. Easy evaluation of soil extracts enables precise nutrient requirement determination.
• Food Industry: The tester is used by quality assurance personnel to check potassium content in beverages and food. These measurements are important for product development, health assessments, and compliance with nutritional labeling requirements.
• Teaching, Research, and Development: By deepening the understanding of potassium’s role in biological and chemical processes, the K-11 serves researchers and educators as a useful tool for experimental studies and educational purposes.
