Memosens CPS171D pH electrodes (photo) can be sterilized and are autoclavable for use in bioreactors, fermenters and other hygienic and sterile applications. The CPS171D measures the full pH range of 0–14 and operates in temperatures from 32 to 284°F. The CPS171D is IECEx and ATEX approved for use in hazardous locations; has IP68 protection; and has FDA, USP and ISO approvals for biocompatibility regarding cytotoxicity and bioreactivity. The CPS171D pH probe has a unique reference gel and glass membrane that when combined, can improve the longterm stability for reliable and accurate measurement, even after multiple clean-in place (CIP) and sterilize-in-place (SIP) cycles. The probe is suitable for CIP and SIP operations up to 284°F. — Endress+Hauser, Greenwood, Ind.
