Key Features

Multiparameter Field Measurement

• The Horiba U-53-10 supports multiple water quality parameters in one portable field instrument.
• Moreover, users can measure pH, pHmV, ORP, dissolved oxygen, conductivity, salinity, TDS, seawater specific gravity, turbidity, water depth, and temperature with one sensor probe.
• In addition, the 10 m cable helps users measure water quality at deeper or harder-to-reach sampling points.
• Furthermore, the meter reduces the need for several separate instruments during field inspection.
• Therefore, users can collect complete water quality data more efficiently during outdoor monitoring.

EPA Method 180.1 Turbidity Measurement

• The U-53-10 includes turbidity measurement with a tungsten lamp source and 90° scattering method.
• Moreover, the turbidity range from 0 to 1000 NTU supports testing in surface water, treated water, wastewater, and environmental samples.
• In addition, the low-range turbidity resolution helps users observe small changes in water clarity.
• Furthermore, the turbidity sensor conforms to US EPA Method 180.1, making it suitable for applications that require this turbidity measurement standard.
• As a result, users can monitor turbidity, suspended particles, and water clarity directly in the field.

Water Depth and Field Operation

• The 10 m cable version supports water depth measurement with a pressure method.
• Moreover, the 0 to 30 m water depth range helps users document sampling depth during field monitoring.
• In addition, the 0.05 m water depth resolution supports practical depth recording during site inspection.
• Furthermore, the 10 m cable gives users more flexibility when testing water at deeper sampling locations.
• Therefore, the U-53-10 helps users record both water quality parameters and sampling depth in one field workflow.

Data Management and Rugged Design
