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.

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.

Horiba LAQUAtwin SALT-11 NaCl / Saltwater (conductivity-based measurement principle) What is salinity? Salinity describes the concentration of dissolved salts in water and is a crucial parameter for the quality of drinking water, the health of aquatic organisms and production safety in the food industry. Our customers appreciate the intuitive operation of the LAQUAtwin SALT-11 and SALT-22 measuring instruments from HORIBA, as well as the accurate measurement results achieved with these portable handheld devices – directly on site and with a minimal sample volume. Precise salinity measurement – the mobile solution from HORIBA The Horiba LAQUAtwin Salz 4ECSalt-11 is a unique, compact measuring device from HORIBA that combines an electrode, display and sample container in a single unit. This enables simple and effective on-site measurements by taking a direct reading from just a single drop. Your pocket laboratory: The only pocket-sized meter that directly measures conductivity in a 0.12 ml sample and converts this into salinity or salt concentration. You do not need a beaker to calibrate the meter or measure a sample. Simply place a few drops of the standard solution or sample onto the sensor. This method saves you time and prevents the wastage of your valuable sample. Why is measuring salinity important? Salinity, i.e. the salt content of a liquid, is a crucial parameter in water quality, environmental analysis and food production. With a HORIBA salinity meter, you can obtain accurate results in real time and reliably monitor key quality parameters – simply, quickly and on the go. In aquaculture & fish farming: Salt content influences the growth, health and behaviour of fish and other aquatic organisms. In agriculture & irrigation: Salinity has a direct impact on soil quality and the uptake of nutrients by plants. In the food industry: Monitoring salt content is crucial for taste, shelf life and compliance with quality standards. In drinking water monitoring: Excessive salinity can impair water quality and must be monitored regularly. Product benefits of the HORIBA LAQUAtwin SALT models: Compact & portable: Ideal for mobile use in the field, laboratory or production environment. Fast results: Measurement using just a single drop of sample – perfect for on-site testing. Precise & reliable: High measurement accuracy for informed decisions in research and practice. User-friendly: Simple calibration, intuitive operation and waterproof design (IP67). Typical applications: Aquaculture & fish farms, agriculture & irrigation systems, food manufacturers & quality control laboratories, drinking water treatment plants & environmental authorities.
