pH measurement in dairies is required for quality and process control purposes. Standard glass electrodes carry the risk of breakage, compromising product safety. With a non-glass pH sensor the hazard is eliminated while measurement accuracy remains high.
This case study discusses how Glanbia Foods Inc. in the USA selected METTLER TOLEDO's InPro 3300 ISFET non-glass pH sensor. They receive accurate and real-time results without any sensor failure or breakage.
Glanbia Foods, Inc. is a division of Glanbia plc, an international food company headquartered in Kilkenny, Ireland. Glanbia Foods is one of the largest producers of cheese and whey products in the United States. In southern Idaho, the company operates two cheese plants, including one for barrel (American-style) cheese, and two separate whey plants. Together these plants use 10.3 million pounds of milk every day, produce 390 million pounds of cheese and 108 million pounds of dairy ingredients annually.
Glanbia Foods process engineers decided upon METTLER TOLEDO’s InPro 3300 ISFET (Ion Selective Field Effect Transistor) non-glass pH sensor. The InPro 3300 ISFET body is constructed out of rugged PEEK FDA-compliant material and has been engineered for hygienic operation. It has been tested and certified to 3A and European Hygienic Engineering & Design Group (EHEDG) standards and is capable of operations up to 130 °C / 266 °F for steam sterilization. The InPro 3300 ISFET’s performance matches its design by providing accurate and real-time results after repeated use and sterilization cycles. An additional benefit is provided by the integral PT 1000 temperature compensating sensor providing back-up readings to the batch RTDs.
