| Abstract: | A new four-beam turbidimeter was designed. The working princip struction of the probe are described. Optical fiber is used for light signal le of the instrument and the contransmission, so that the interference of bubbles in sample, backeground color and stray light is avoided effectively. The adoption of duallight source and dual-photoelectric detector design eliminates the influence of the aging of photoelectric devices and bubbles in water on the measurement results and the precision and stability are improved considerably. The instrument can be used for on-line measurement. |
