Product Description
Description
The SC7440 Sensor is a measuring system best suited to continuously and consistently measure the turbidity using a nephelometric measurement of scattered light in accordance with ISO 7027. The SC7440 sensor uses LED optical technology to provide an ex-tremely stable, accurate, low maintenance sensor.
The sensor uses a measuring method that compares transmitted light with scattered light. The sensor is designed with due care to the arrangement of the optical system. These design makes the sensor less susceptible to disturbing light.
