The mounting location must be such that sediments or gas bubbles cannot accumulate by the refractometer. Good flow velocity is essential in keeping the prism clean.
| CAUTION If the process pipe vibrates, support the pipe. A vibrating pipe can damage the in-line refractometer mounted on it. |
The refractometer cover should not be exposed to high temperature radiation. In most cases, draft and natural convection provide sufficient air cooling if the air gets to flow freely around the refractometer head.
| CAUTION Always mount the refractometer so that the interconnecting cable points downwards from the refractometer head. |
