Horiba LAQUAtwin S030 Potassium Ion Replacement Sensor for K-11 tester

Mobile Analysis Laboratory for Ion Measurements – Versatile Use Compact kit for simultaneous determination of multiple water and environmental parameters The Horiba 4M LAQUAtwin Kit is a mobile laboratory that allows you to determine important ion parameters directly on-site. The case contains pocket testers for measuring sodium, potassium, nitrate, and calcium, as well as for temperature measurement. Each device uses ion-selective electrodes for targeted analysis of small samples and provides fast, reliable results. In addition to the four measurement devices, the kit includes calibration solutions and a wash/spray bottle for sensor cleaning. The sensors can be stored dry without special storage solutions. Compact Multi-Parameter Kit for Flexible On-Site Analyses The set is designed for measurement tasks where multiple ions need to be detected simultaneously, for example when monitoring drinking and process water, performing environmental checks of water bodies, conducting aquaculture analyses, or agricultural research. Thanks to the case, all essential testers including accessories are always on hand and ready for immediate use. The measurement results are available in a short time and are reliable and reproducible – ideal for routine and control measurements in the field. All components are neatly arranged in the case and ready for use at any time. An additional advantage is that the sensors can be stored dry without special storage solutions. Due to its compact design, the kit is particularly suitable for mobile applications where multiple ion parameters need to be determined quickly one after the other or in parallel. Why Multi-Parameter Ion Measurements Are Useful – and a Mobile Kit Is Ideal In many applications, not just a single measurement is important, but the interaction of multiple ion parameters. Sodium, potassium, nitrate, and calcium together influence water quality, biological processes, plant growth, and technical operations. Single measurements in a laboratory are often time-consuming and inflexible. A mobile analysis kit allows simultaneous detection of multiple parameters directly on-site. This allows relationships to be recognized more quickly, decisions to be made more reliably, and measurement campaigns to be carried out more efficiently. The Horiba 4M LAQUAtwin Kit combines these advantages in a compact, user-friendly system. Additional information We would like to inform you of an upcoming product update for the LAQUAtwin handheld analysers. To enhance product safety and prevent infants and young children from accidentally swallowing the batteries, HORIBA will be introducing a new battery cover on all LAQUAtwin pocket-sized analysers. Overview of the product change Change: Battery cover for enhanced safety. Reason: To prevent accidental swallowing of batteries. Production date: From January 2026 in Japan Deliveries to EMEA distribution partners: From March 2026 As this change is currently being rolled out, mixed deliveries of the current and updated versions may occur during the transition period. Frequently asked questions How long is the warranty period for HORIBA pocket testers? The warranty period is two years from delivery for commercial customers. How many measurements can be taken before the sensor needs to be replaced? This varies depending on the application, use and storage of the Horiba tester. As a rule, the sensor should be replaced after one year. How long is the warranty period for replacement sensors for pocket testers? The warranty period is 12 months after delivery for commercial customers. How do you clean the pocket tester? The pocket tester can be rinsed under water. We recommend cleaning with DI water (deionised). Tissue paper is recommended for drying after cleaning. How can the pocket tester be reset to factory settings? (e.g. in the event of an incorrect measurement result) This information can be found in the operating instructions. These can be found in the download area of the shop and on the product. Is calibration necessary before each measurement? Basically, yes. Further information can be found in the operating instructions.

Precise Potassium Ion Measurement on the Go – Mobile, Reliable, and Easy Precise potassium ion measurement with 2-point calibration and integrated temperature display 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.
