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

Horiba U‑54‑2 Multi‑Parameter Water Quality Meter U‑54 with 2 m Cable

The Horiba U-54-2 is a professional-grade water quality analyzer from Horiba’s U-50 series, engineered for versatile and accurate on-site water quality assessment. It integrates several high-precision sensors into a single rugged probe connected via a 2 m cable for convenient sampling. This model is ideal for environmental field surveys, water resource monitoring, aquaculture, wastewater assessment, and industrial applications where comprehensive water quality data is needed quickly and efficiently.

Built for robustness and ease of use, the U-54-2 features a waterproof control unit with a clear, backlit LCD display, one-hand operation, and automatic calibration functions to simplify setup and reduce measurement time. The unit supports data logging and USB connectivity for exporting measurement data to a PC for reporting and further analysis.

Key Features

• Measures up to 11 water quality parameters simultaneously using one integrated sensor probe from the U-50 series.

• 2 m cable for flexible, easy sampling in on-site conditions.

• Rugged, waterproof construction suitable for field use with a backlit LCD display for clear readings.

• Automatic calibration capability that simplifies setup and improves measurement reliability.

• Intuitive on-screen icons showing battery status, probe connection, and USB connectivity.

• Quick-connect cable and field-replaceable sensors for easier maintenance.

• Data logging and USB interface for exporting stored data to a PC.

Typical Measured Parameters

The U-54-2 typically measures:

• pH (acidity/alkalinity)

• Oxidation-Reduction Potential (ORP)

• Dissolved Oxygen (DO)

• Conductivity (COND)

• Salinity
