LANGE 1720 E sc

The profile

The model 1720 E Low range turbidimeter reflects an astounding 45 years of worldwide leadership in turbidity measurement science.
The new 1720 E sc bypass sensor is a precise measuring device for the turbidity measurement of ultraclear up to medium turbid media.
The "E-model" guarantees optimum filtration control for municipal and industrial water processing plants.
The display and the further processing of the measured data for one or two sensors is performed by the SC 100 Universal Controller.
