3.1 Mounting & Site Selection
The instrument is designed for wall mounting. If wall mounting is not practical, the
instrument can be mounted on any suitable level surface. For ease of service there should
be about 45cm (18”) free area above the instrument; this will ensure enough room for
calibration and cleaning the optical well. Choose a location that is easily accessible for
operation and service and ensure that the front display rests at eye level. The overall
mounting dimensions of the instrument are shown in Figure 3. The recommended
mounting screws (four are required) are M6 (or ¼”).
Figure 3: Overall Mounting Dimensions of the Instrument
It is critical that the instrument be mounted as close as possible to the sampling point to
ensure an accurate reading of turbidity (within 6-10 ft of the sampling point).
