Installation overview
Figure 3 shows an example of the probe installation with a chain holder option. Figure 4 shows an
example of the probe installation with a flow cell option. Refer to the installation documentation to
install the sensor.
Put the probe into the sample. Make sure that the optical path is fully immersed in the sample. Install
the sensor transversally to the flow direction of the sample so the particle on the windows are at a
minimum and the nano-layer function gives the optimum support. Refer to
Figure 5 .
Note: Make sure that the probe does not touch the ground.
