Horiba U-53 Multiparameter Water Quality Meter ground probe The Heron Conductivity+ combines aThe HORIBA U 53 is a field portable multiparameter water quality meter built around a tungsten lamp turbidity sensor, delivering ten simultaneous measurements from one submersible probe. The difference between the U 53 and the U 52 is the turbidity light source. The U 53 uses a tungsten lamp rather than an LED the configuration specified by turbidity methods that call for a white light incandescent source. If your sampling program or discharge permit
