Horiba COMPACT LAQUAtwin pH-33 pH-mV Meter

Horiba COMPACT LAQUAtwin pH-33 pH-mV Meter with Temperature Display (±0.01 pH Accuracy, 5-Point Calibration)

The Horiba COMPACT LAQUAtwin pH-33 pH-mV Meter is a high-performance, pocket-sized analyzer designed for precise pH, millivolt (mV), and temperature measurements using minimal sample volume. Delivering an accuracy of ±0.01 pH, the pH-33 supports demanding analytical tasks that require excellent precision and measurement stability.

This model features up to 5-point pH calibration, allowing users to calibrate across a broad pH range with higher confidence and improved accuracy in real sample conditions. The built-in temperature display enables temperature monitoring during measurement, supporting better result interpretation and quality control.

Powered by Horiba’s LAQUAtwin flat sensor technology, the pH-33 measures tiny liquid volumes, droplets, or samples placed directly on the sensor surface—without beakers or electrodes. Its compact and portable design makes it ideal for laboratory work, field testing, food and beverage analysis, environmental monitoring, and on-site quality control.
