Design and Performance that Makes Measurement Easy in a Variety of Applications

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.

Measurements in Surface Water: The long 30 meter cable option allows the user to deploy the sensor probe unit and collect measurement data at varying depths. The GPS models facilitate environmental surveys of oceans, lakes and rivers.

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 transferred to a PC later.
