Product Overview

The Horiba U-50 Series multi-parameter water quality meters are equipped to measure and log data for as many as 11 parameters simultaneously with one single probe. Experience the durability, reliability and intuitive software that will exceed your expectations. Monitor surface water and ground water by deploying the probe directly into a body of water or using a flow cell.


One probe, one 500-mL bottle of pH 4.0 buffer solution, one 250-mL bottle of KCl solution, DO sensor installation set, cleaning brush, calibration cup, batteries, shoulder strap, and carrying case.



More About the

Easy to Operate

This handheld, waterproof meters feature a large 3-1/2" (8.9 cm), easy-to-read LCD with backlighting for use in dark and low-light conditions. Multiple parameters can be measured and displayed at the same time. USB/probe connectivity and battery power are also indicated via the display. Variable contrast allows you to adjust for extreme ambient light conditions.

Meters are designed for one-handed operation. Probes are attached via a quick-connect connector allowing for fast setup. The unique auto-calibration feature provides a hassle-free meter setup. Turbidity sensor offers better accuracy than most other conventional water quality meters. Polarographic DO sensor features improved stability, fast response, and easy maintenance.

Auto-hold function freezes average data values providing more time to verify or transcribe data. Up to 10,000 data sets can be stored and later transferred to a PC via a built-in USB connection. Units of measure are user selectable which helps you save time.
