The mounting location needs to 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 might damage the in‑line refractometer mounted on it. |
Do not expose the refractometer cover 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.
