1. , based on the high-sensitive multifunction analyser of backward scattered light technology, it is characterized in that:

  • this analyser is made of detection probe, the Lights section, input and amplifier section and display part, wherein,Detection probe is a rear light scattering signal inductive probes, form by liquid container and signal transmission fiber group, liquid container has lighttight base, design has two drainages to discharge the aperture of mensuration liquid and insertion optical fibre set on base, liquid container is high tubular, inside surface is smooth, outer blacking;

    The signal transmission fiber group is made up of two groups of optical fiber, one group is exciting light optical fiber group, another group is detection signal Transmission Fibers group, two groups of optical fiber also together, θ

    inserts from probe mount with angle, and θ

    is the angle of optical fiber and base, 0 °



    θ



    90 °

    or 90 °



    θ



    180 °

    , two groups of optical fiber are coupling in respectively on light source and input and the amplifier, form the backward scattered light analyzing and testing system of 180 degree;

    , be coupled with it as light source with semiconductor laser by the excitation fiber group of detection probe;

    It is detecting signal unit that input and amplifier section adopt silicon photocell.Its output signal connects common amplifying circuit and comes amplifying signal;

    Digital display screen is adopted in the display part, is connected with the output terminal of signal amplification circuit.
