Horiba U‑53G‑10 Multi‑Parameter Water Quality Meter

Horiba U‑53G‑10 Multi‑Parameter Water Quality Meter with GPS & 10 m Cable

The Horiba U-53G-10 is a rugged, field-ready multiparameter water quality meter from the U-50 series, equipped with a GPS module and a 10 m cable for extended reach in water sampling. It enables simultaneous measurement and data logging of critical physical and chemical parameters using a single integrated probe. The built-in GPS functionality allows accurate geolocation of measurement points, enhancing data traceability and reporting for environmental assessments, regulatory compliance, scientific research, and industrial water quality monitoring.

The instrument features a waterproof control unit with a backlit LCD screen that displays all measured parameters clearly, even in low-light conditions. Automatic calibration simplifies setup for key measurements, while field-replaceable sensors and robust design reduce maintenance time and costs.

Key Features

• Simultaneous measurement and display of up to 11 water quality parameters with one sensor probe.

• Integrated GPS functionality for geotagging data points.

• 10 m cable for deeper or hard-to-reach sampling locations.

• Waterproof and shock-resistant control unit with backlit LCD display for enhanced visibility in the field.

• Automatic calibration features for reduced setup time and accurate results.

• Data logging capability with internal memory for storing up to 10,000 sets of measurements (date/time and GPS included).

• USB connectivity for data transfer to a PC (via optional cable and software).

• Field-replaceable sensors for efficient maintenance.
