The Cleanfit CPA875 pH retractable assembly provides reliable protection against bacterial contamination of processes, thus making it suitable for safe, automated pH measurement in sterile processes. The Cleanfit assembly is made of 1.4435/316L stainless steel with smooth, electropolished surfaces (Ra less than 0.76), and seals manufactured according to U.S. Food and Drug Administration (FDA) class VI. The newly designed rinse chamber and dynamic seal allow movement of the assembly in and out of the process free from interference. For demanding applications and highly toxic chemicals, a double chamber is available as an added safeguard. The new assembly meets all standard regulations for the life sciences and food industries. The Cleanfit can be installed directly in a pipe or on a boiler. — Endress+Hauser Messtechnik GmbH & Co. KG, Weil am Rhein, Germany
