4.2.3 Prism wash nozzles
When selecting a wash nozzle for a compact refractometer, take into account both
the wash medium and the lowcell model: lowcells with larger pipe diameters need
longer wash nozzles. Figure 4.7 below shows a wash nozzle for a lowcell and gives
the measurements and part numbers for each nozzle type.

Figure 4.7 Wash nozzles for owcell AFC-HSS-XXX-XX-NC
Figure 4.8 shows how the nozzle is mounted in a low cell (-NC with stud for a wash
nozzle). Note: See Section 9.3.5 for more information on lowcells.
For probe refractometers, select the wash nozzle according to wash medium and
refractometer model, see Table 4.1 below.
Figure 4.9 shows the mounting of the wash nozzle for Sanitary probe refractometer
PR-23-AP. Figure 4.10 shows the mounting of the wash nozzle for Process refractome-
ter PR-23-GP.
