Horiba Sodium (Na⁺) Pocket Testers – Measurement Solutions for Determining Sodium Ions

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.

Mobile Sodium Ion Tester from Horiba with Temperature Measurement – precise and robust High-precision sodium ion tester with 2-point calibration – ideal for water and environmental analysis The Horiba LAQUAtwin Na-11 sodium ion tester was specifically designed for accurate measurement of sodium concentrations in a wide range of samples. The device enables direct on-site measurements. Its clear display shows both the Na⁺ concentration and the sample temperature in a single step, making field, laboratory, and greenhouse work significantly more efficient. Mobile sodium ion tester for precise on-site measurements Featuring 2-point calibration and automatic standard recognition (150 and 2000 ppm), the instrument can be easily adapted to different measurement requirements. The integrated temperature display and automatic temperature compensation ensure accurate results even under fluctuating environmental conditions. The robust IP67 housing is dustproof and waterproof, making the tester suitable for demanding daily use. With a battery life of approximately 400 hours, reliable long-term operation is ensured. The tester is supplied with standard solutions, sampling sheets, batteries, and matching pipettes for immediate use. Why sodium measurement matters – and why a handheld tester is the ideal solution Measuring sodium ions plays a crucial role in water, environmental, food, and agricultural analysis. Excessively high or low sodium concentrations can significantly affect water quality, soil structure, plant growth, and the quality of food products and drinking water. Regulatory limits and quality standards further require regular monitoring. A mobile sodium ion handheld tester enables fast and precise analysis directly at the point of use, without time-consuming sampling or laboratory analysis. The Horiba LAQUAtwin Na-11 combines this flexibility with high measurement accuracy and ease of use, making it ideal for routine monitoring, quality control, and research applications. Typical applications for the Horiba sodium ion tester Environmental monitoring: Measurement of sodium concentrations in surface and groundwater to assess water quality and ensure compliance with environmental standards. Food and beverage production: Testing sodium levels in food and beverages for quality assurance, product development, and regulatory compliance. Agriculture: Monitoring sodium content in irrigation water and soils to support plant health and optimize water management. Research & development: Use in laboratories for experimental studies on sodium ion behavior under varying conditions. Education: Utilized in schools and universities to demonstrate the use of ion-selective electrodes in analytical chemistry.
