Horiba U-50 Series Replacement Sensor Probe with Cable Assembly

Replacement sensor probe and cable assembly for the HORIBA U-50 Series multiparameter water quality meters. This is the probe only, supplied without a control unit — so you can replace a damaged or worn probe, change cable length, or run a second probe without buying a complete meter. Each assembly ships with the probe guard and conductivity cell already fitted. It connects directly to an existing U-50 Series control unit, so a swap takes minutes in the field and gets a downed instrument back into service the same day. What's included Sensor probe with integrated cable assembly Sensor probe guard Conductivity cell Water depth sensor — U-52G and U-53/U-53G assemblies only Choosing the right probe Match the assembly to your control unit model, then pick the cable length for your deepest measuring point: 2 m for surface water, flow cells and beaker work, 10 m for typical shallow monitoring wells, 30 m for deep wells, reservoirs and full water-column profiling. The U-53 and U-53G share a single probe assembly.
