Description
Overview
GAOTek high-temperature pH sensor is designed with a double-chamber reference system of high temperature-resistant gel and solid electrolyte as well as fully suitable for high-temperature service with a stable precise pH measurement and low maintenance. It is mainly focusing on bio-fermentation, pharmaceutical, chemical, food, beverage, and starch process applications due to its special pH glass and reference system design for CIP or SIP autoclavable and sterilizable up to 266 °F (130 ℃).
