The probe refractometer PR‑43‑AP is primarily designed for mounting in a tank wall. To ensure that the measurement is representative and that the prism stays clean, install the probe close to a stirrer.

Probe refractometer type PR‑43‑AP‑H25 is connected to the process by a 63.5 mm (2.5 in) sanitary clamp.

For higher process (or ambient) temperature, use instead a flush mounted refractometer, where the electronics in the refractometer head are farther away from the process heat.

The refractometer type PR‑43‑AP‑T10‑L00 is flush mounted using a sanitary APV tank bottom flange. The refractometer can be flush mounted in the side wall, which allows the use of a scraper. It is also easily installed through a steam jacket.
