Food manufacturer Colona relies on Endress+Hauser’s non-glass pH sensors.
Safety first: Food manufacturer Colona relies on Endress+Hauser’s non-glass pH sensors.

What does it to take to safeguard product quality and strengthen customers’ trust? This question was on the mind of Colona, Belgium’s largest independent manufacturer of emulsified sauces. The family-owned company must meet growing certification requirements in the retail trade.

For Colona, the pH value is at the heart of the quality assurance process. It shows whether the vinegar content is sufficient to ensure the sauces have a long shelf life. In the past, samples were taken from the sauces and then analyzed in the lab. The company now performs continuous in-line monitoring of this key parameter during production with the Ceramax pH sensor from Endress+Hauser.

Colona was persuaded by the non-glass, break-resistant sensor, its hygienic design and high precision. Memosens technology allows to calibrate the sensor in the lab. “Optimization of the pH measurement with the Ceramax is the next step in our quality-oriented approach. It provides us and our customers a high level of assurance and reliability and is an invaluable aspect of the traceability of our products,” says CEO Philippe Colon.
