Horiba U-52 | Multi-Parameter with Flow Cell | Water quality testing | Water quality monitoring | Water testing equipment

Product Overview

The Horiba U-52 Multi-parameter water quality checker enables a user to measure up to 11 parameters simultaneously with just one unit. Tough and powerful design, and a consideration for user friendly field monitoring of river, ground water, drainage water, and more, brings together both function and performance, which allows a simple operation for every user.

Product Features:

• High sensitivity turbidity sensor incorporated.
• A membrane cap for stress free maintenance of the dissolved oxygen sensor.
• A hand-held transmitter and sensor probe – designed for easy one-handed operation and data confirmation.
• One touch calibration makes routine calibrations for pH, DO, conductivity, turbidity and water depth a breeze.
