The probe refractometer PR‑23‑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‑23‑AP‑T is connected to the process by a 2.5 in sanitary clamp. PR‑23‑AP‑R is connected by a 4 in sanitary clamp.
| CAUTION For higher process (or ambient) temperatures, use instead a flush mounted sensor, where the electronics in the sensor head are farther away from the process heat, see Flush mounting probe refractometer PR‑23‑AP‑XX‑PSS. |
The refractometer type PR‑23‑AP‑XX‑PSS is flush mounted, using a sanitary APV tank bottom flange. The sensor can be flush mounted in the side wall, which allows the use of a scraper. It is also easily installed through a steam jacket.
