- Optional Flow-Cell available for low-flow sampling
- View all readings on one screen
The U-50 Series multi-parameter water quality meters are equipped to measure and log data for as many as 11 parameters simultaneously with one single probe. Experience the durability, reliability and intuitive software that will exceed your expectations. Monitor surface water and ground water by deploying the probe directly into a body of water or using a flow cell.

Measurement at a Drainage Ditch or Wharf
Instantaneously monitor, collect and store data while moving the submersed sensor probe unit
Measurement in Marshes
The control unit's waterproof design allows the user to work without concern of splashing or accidentally dropping the control unit in the water. The backlight display allows the user to take measurements in the dark.
Measuring Ground Water from an intake
With the sensor probe lowered and submersed at an intake, 10,000 data sets can be stored in the control unit and transfered to a PC later.
Measurements in Surface Waters
The long 30 meter cable option allows the user to deploy the sensor probe unit and collect measurement data at various depths. The GPS models facilitate environmental surveys of oceans, lakes and rivers.
