Excalibur HY 25 (Hygienic 3-A)

3-A Certified Transmission Probe for Efficient Control of Production Processes in Hygienic Applications

Requirements on hygienic production processes are constantly rising, especially in the food and pharmaceutical industries. The Excalibur 3-A transmission probe from Hellma is of interest to everyone who has an eye on process or cost optimization such as product and project managers, or R&D and PAT engineers, both on the user side in the industry or with system integrators who support them.

With its special features, this product is designed primarily for the milk processing industry which imposes some of the most stringent hygienic requirements. Beyond that, it is also ideally suited for the analysis of many other liquids in the food industry.

Legal Compliance

The most established standard in this context is the US 3-A sanitary standard. The hygiene criteria defined therein were originally defined for the dairy industry. They set some of the highest standards for technical plant equipment and allow it to be used in many other areas and different countries.
