Horiba U-50 Series

Multiparameter Water Quality Meters

Magnify

Use the Horiba U-50 series multiparameter water quality meter to simultaneously measure and view the monitoring result of up to eleven parameters, including pH, oxidation reduction potential (ORP), dissolved oxygen (DO), conductivity, salinity, total dissolved solids (TDS), seawater specific gravity, temperature, turbidity, and water depth, with one device. GPS capabilities are included with the U-52G and U-53G. View the specifications sheet for more information about ranges, resolution, repeatability, and accuracy for all parameters.

The U-50 series control unit features a shock-resistant cover, one-handed operation of all functions and an easy-to-read backlit LCD with on-screen display of measurement parameters, battery power, GPS, USB connectivity, probe unit connectivity, and on-screen instructions. A quick connect feature allows the U-50 control unit cable to be easily and quickly connected or disconnected. All 11 parameters are displayed simultaneously on screen, a larger font size is available, and variable display technology compensates when used in extreme ambient lighting conditions. The U-50’s auto-calibration feature facilitates trouble-free calibration of conductivity, pH, DO, depth, and turbidity.

U-50 series sensor probe features include chemical resistant materials and construction, field replaceable sensors, an ultra-sensitive turbidity sensor (high sensitivity available for U-53 and U-53), a dissolved oxygen sensor with screw-on-type membrane cap which requires minimal maintenance, and an optional ToupH pH electrode which is difficult to break. Data management features of the U-50 include an auto-hold function to freeze average data values so they can be transcribed easily, a diagnostic function which notifies the user of errors, selective measurement units so the operator can report data without converting units, and a USB connection for interface with and data management through a PC.

The U-50 Series includes the U-51, U-52, U-52G, U-53, and U-53G (comparison). Ideal for uses such as measuring at draining ditches and wharfs, marshes, surface water, and ground water from an intake.
