Horiba U‑54G‑2 Multi‑Parameter Water Quality Meter

Horiba U‑54G‑2 Multi‑Parameter Water Quality Meter

The Horiba U-54G-2 is a high-performance multiparameter water quality meter from the U-50 Series, engineered for reliable field measurements and precise location-based data collection. It integrates multiple sensors into a single rugged probe and includes built-in GPS functionality, allowing each measurement to be automatically tagged with geographic coordinates.

With a compact 2 m cable, the U-54G-2 is ideal for surface water testing, river monitoring, groundwater assessment, wastewater evaluation, and industrial water quality analysis. The waterproof control unit features a backlit LCD display for clear visibility in outdoor environments, while automatic calibration functions help ensure accurate and repeatable results. Data logging and USB connectivity support efficient data storage and transfer for reporting and analysis.
