Features

DKK Turbidity TB-31 Sensor Features

High accuracy - The unit provides high accuracy in low concentration regions.
Power Saving design - This instrument has a power-saving design requiring only two AA alkaline batteries for approximately 120 hours of continuous measurement. A rechargeable battery can also be used.
Functional operation- The sensor can directly be immersed into the sample water which makes it possible to monitor turbidity for one day (24 hours or less)
Simple data recording - It comes equipped with 1000 data memory function. You can also connect the meter to a personal computer or printer for easy and accurate recording of measurement data.
Waterproof construction - The unit is capable of measuring turbidity at depths of up to 100 meters. The LCD display shows all appropriate parameters, and the instrument features an easy-to-follow calibration procedure.
