Tel-Tru's P331 is 3A compliant and designed for CIP/SIP systems.

Key feature of the sensing element is advanced temperature compensation methods, which not only improves performance over a wide temperature band, but greatly reduces CIP/SIP recovery times.

The P331 is manufactured for reliability and stability in high humidity environments, and where direct sprays for wash-down purposes are present.

The P331's construction of all 316L SST makes it an ideal choice for applications involving aggressive fluids.
