Horiba U‑53G‑30 Multi‑Parameter Water Quality Meter

Horiba U‑53G‑30 Multi‑Parameter Water Quality Meter with GPS & 30 m Cable

The Horiba U-53G-30 is a rugged handheld water quality analyzer from the U-50 Series, designed to deliver accurate, on-site multiparameter measurements. It combines multiple sensor technologies in a single probe and features integrated GPS for automatic location tagging of each measurement point. The extended 30 m cable provides flexibility for sampling deeper waters or hard-to-reach environments without repositioning the control unit. Ideal for environmental professionals, researchers, regulatory agencies, and industrial monitoring tasks.

Constructed for field durability, the U-53G-30 includes a waterproof, shock-resistant control unit with an easy-to-read backlit LCD display. Automatic calibration aids faster setup in the field, and data logging capabilities allow efficient data management with USB transfer to a computer.

Key Features

• Simultaneous measurement and display of up to 11 water quality parameters via a single integrated probe.

• Built-in GPS for geotagged measurements and enhanced data tracking in the field.

• 30 m cable for extended reach into deeper or challenging sampling locations.

• Waterproof, rugged field housing with backlit LCD for visibility in various lighting conditions.

• Automatic calibration functions to speed up setup for key parameters.

• Data logging capacity with storage (typically up to 10,000 sets of measurements including GPS coordinates).

• USB connectivity for exporting logged data to a PC.

• Field-replaceable sensor modules for reduced maintenance and long operational life.
