The E+H Tophit CPS471D pH sensor is designed for hygienic applications. It features a double chamber reference system with contamination-resistant and polyacrylamide-free gel, which guarantees stable measurement. Because the CPS471D can be used at low temperatures, response time is shorter and accuracy is consistently higher. The sensor features longer calibration intervals than glass electrodes, which results in lower hysteresis with alternating temperatures, low measuring error after high-temperature loading, and almost no acid and alkaline errors. It also offers certified biocompatibility and a built-in temperature sensor for effective temperature compensation. The CPS471D has an unbreakable PEEK shaft, and it is sterilizable and autoclavable. It is ideal for clean-in-place (CIP) processes when combined with an automatic retractable assembly.

The CPS471D sensor features Memosens digital technology. Memosens sensors offer greater process and data safety, easy handling, and predictive maintenance. The non-contact inductive signal transmission eliminates problems associated with moisture, such as corrosion and distortion. The intrinsically safe electronics allow application in hazardous areas. Since measured values are transmitted digitally, data is free from interference and errors are immediately detected. Sensors with Memosens technology also have integrated electronics that store calibration data and operating information, allowing for calibration separately from the measuring point and protected from the effects of weather. Maintenance intervals can be defined based on all stored sensor load and calibration data.
