Horiba LAQUAtwin S010 pH Replacement Sensor for pH-11, pH-22, pH-33 tester

Mobile pH Tester with 3-Point Calibration for On-the-Go Use Horiba LAQUAtwin pH Tester – ideal for water and environmental analysis The Horiba LAQUAtwin pH Tester pH-22 is compact, robust, and designed for mobile use. With up to three calibration points and a measurement range of 0.00 to 14.00 pH, this device delivers high precision and reliability. Direct measurement with just a single drop of sample provides fast results. Features such as automatic buffer recognition, temperature compensation, and Stabil/Hold functionality make daily operation simple and convenient. Mobile precision pH tester for reliable on-site measurements The tester combines electrode, display, and sample container in a dust- and waterproof IP67 housing, making it ideal for field and laboratory applications. The digital backlit display shows pH and mV values clearly and accurately. Automatic shut-off and battery status indicators ensure convenient operation. The package includes calibration buffer solutions (pH 4.01 and 7.00), batteries, a pipette, and a quick-start guide. Why accurate pH measurement is critical – and why a handheld tester is ideal pH is a key parameter in water, environmental, and process analysis because it significantly influences chemical reactions, biological processes, and material stability. Even small deviations can substantially impact water quality, product quality, or process safety. A mobile handheld pH tester allows fast, reliable measurements directly on site. Changes can be detected immediately, and corrective actions implemented without delay. The Horiba LAQUAtwin pH-22 combines this flexibility with high measurement precision, making it ideal for field, laboratory, and routine applications. Typical applications for the Horiba LAQUAtwin pH handheld tester Aquaculture and coral monitoring Beer, beverage, and food production Heating systems Laboratories and schools Environmental analysis Water treatment Horticulture 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.
