HORIBA U-50 series water quality analyser

Tuesday, 26 May, 2015 | Supplied by: HORIBA


The HORIBA U-50 series enables accurate and simultaneous measurement of up to 11 water quality critical parameters with a single probe. The control unit features a shock-resistant casing which can display the following parameters on-screen simultaneously: pH; oxidation reduction potential (ORP); dissolved oxygen (DO); conductivity; salinity; total dissolved solids (TDS); seawater-specific gravity; temperature; turbidity; and water depth.

The meter is designed for single-handed operation of all functions and has an easy-to-read backlit LCD screen, providing display of the measured parameters, battery power, GPS, USB connectivity, probe unit connectivity and on-screen instructions. Auto calibration facilitates trouble-free calibration of conductivity, pH, DO, depth and turbidity, which can be done with a single calibration solution and with the press of a single button.

Data management features include an auto-hold function to freeze average data values so they can be transcribed easily or logged to memory; 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 through a computer.

Additional features are: chemical-resistant materials and construction; field-replaceable sensors; an ultrasensitive turbidity sensor (high sensitivity available for U-53, U-53, U-54 and U-54G); a dissolved oxygen sensor with screw-on membrane cap (requiring minimal maintenance); and an optional, durable pH electrode.

The user can choose a 2, 10 or 30 m cable length. The cable can be easily connected and disconnected using the quick-connect fitting. A GPS option is also available on the U-52G, U-53G and U-54G models to track the locations of field measurement data.

The product is designed to be both rugged and easy to operate, making it suitable for measuring the water quality in water treatment plants, discharge and drainage water, surface water (eg, lakes, rivers and sea), groundwater and aquaculture.
