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.
