General Features
- Various sensors have been consolidated into a single probe: Simultaneous measurement and display of up to 11 parameters are possible. The sensors can be individually replaced. However, only one type of standard solution is required.
- Can be easily operated by anybody: Equipped with a one-touch automatic calibration function. The cable connection is an easy-to-attach/detach one-touch type. The data is conveniently displayed in real-time through the Auto-Hold function, allowing for easy visual monitoring during measurements. Furthermore, it is equipped with a diagnostic function that indicates the replacement timing of each sensor and displays errors.
- Easy and convenient data management function: Easy computer integration is possible with USB connectivity.
- The LCD display makes it easy to read and operate: The data is displayed clearly on the LCD screen for easy viewing. Possible to operate easily with one hand. Various functions are displayed with easily recognizable icons.
- Convenient for field measurements: Designed for field measurements, it having been enhanced with impact resistance using soft resin materials. Also equipped with a convenient carrying bag as a standard accessory.
- The turbidity sensor (U-53) is compliant with EPA Method 180.1: The U-53 incorporates a turbidity sensor that is compliant with EPA Method 180.1. Equipped with a wiper.

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.
