Horiba COMPACT LAQUAtwin pH-22 pH-mV Meter

Horiba COMPACT “LAQUAtwin” pH-22 pH-mV Meter (±0.01 pH Accuracy, 3-Point Calibration)

The Horiba COMPACT LAQUAtwin pH-22 pH-mV Meter is a high-precision, pocket-sized instrument designed for fast and accurate pH and millivolt (mV) measurements with minimal sample volume. With an accuracy of ±0.01 pH, the pH-22 supports reliable analysis for applications that demand higher precision than basic pH meters.

This meter features 3-point pH calibration, allowing users to calibrate across a wider measurement range using standard buffer solutions. As a result, it delivers improved accuracy and stability in real-world samples. In addition to pH, the pH-22 measures mV values, enabling ORP measurements and electrode diagnostics.

The LAQUAtwin pH-22 uses Horiba’s flat sensor technology, which allows direct measurement of small liquid volumes, droplets, or samples placed directly on the sensor surface. The compact, waterproof design makes it suitable for laboratory work, field testing, education, food and beverage analysis, and on-site quality control.
