Horiba U-53 Datalogging Multiparameter Water Quality Meter

Horiba’s U-53 is a multiparameter water quality meter that measures and displays up to 10 parameters simultaneously, including pH, ORP, dissolved oxygen, conductivity, salinity, TDS, seawater specific gravity, temperature, turbidity (with Tungsten lamp), and water depth. The turbidity sensor conforms to USA EPA method 180.1 and provides a resolution to 0.01 NTU.

The U-53 can be used anywhere: measuring at drainage ditches, groundwater intakes, or measuring environmental water sources like oceans, lakes, rivers, or marshes. The waterproof design lets you work anywhere without concern for splashing, and the backlit display makes it possible to work in low-light or dark environments.
