As the food, beverage, and pharmaceutical industries continue to evolve, the need for accurate and rapid quality control measures has become increasingly important. One key tool in this effort is an in-line Visible and near-infrared (NIR) spectroscopy probe, which can quickly analyze samples for a variety of important quality, safety, and regulatory metrics. However, not all in-line NIR spectroscopy probes are created equal and for the most demanding applications, a 3-A certified probe is essential.

What truly sets tec5USA’s immersion probe apart from all other manufacturer’s probes is the robust 3-A certified hygienic construction meaning it can be left in place and withstand the temperatures and chemicals experienced in food and pharmaceutical clean in place recipes.

So what exactly is a 3-A certified NIR probe, and what benefits does it offer for food and beverage applications? Let’s take a closer look.

First of all, it’s important to understand that 3-A is a widely recognized industry standard for hygienic design and material construction in food and pharmaceutical processing equipment.

This tec5USA probe is compliant with the 3-A Sanitary Standards organization ensuring that it meets the highest requirements for sanitation and safety.

Use a 3-A certified tec5USA in-line probe to obtain real-time quality information about your process and automatically optimize processing controls.

Why does this matter for in-line NIR spectroscopic probes? Food and pharmaceutical samples can be quite complex and diverse, and it’s essential that any equipment used to analyze them be able to handle a wide range of conditions and substances without risking contamination or cross-contamination.

The tec5USA 3-A certified probe has been designed specifically with these considerations in mind, built with electropolished stainless steel and FDA CDR 21 compliant food contact materials that minimize the risk of contamination and make it easy to clean and maintain. The probe is easily installed into a leak-free, sanitary triclamp fitting and can be left in place during CIP/SIP cycles.

In addition to its hygienic benefits, the tec5USA 3-A certified NIR probe also offers a number of advantages in terms of performance and accuracy. Because it has been designed to meet the rigorous demands of the food and beverage industry, a 3-A certified probe is more likely to provide reliable and consistent results, even in challenging conditions. This can be particularly important for applications where small variations in composition can have a big impact on final product quality.

The tec5USA NIR immersion probe can measure multiple chemical components simultaneously to generate actionable real-time data. Online, non-destructive testing provides the ability to perform real-time processing monitoring and automated closed loop control. These benefits can help improve the efficiency and effectiveness of food and pharmaceutical manufacturing and ensure quality and safety of the final product.

Finally, it’s worth noting that choosing this tec5USA 3-A certified NIR probe can be a smart business decision. By investing in high-quality equipment that meets industry standards for safety and performance, you can reduce the risk of product recalls, improve quality control measures, and ultimately enhance your reputation among customers and partners.

In summary, if you’re looking for a NIR immersion probe for food, beverage, or pharmaceutical applications, a tec5USA 3-A certified probe is the way to go. By offering superior hygiene, accuracy, and performance this probe can help ensure that your products meet the highest standards of quality and safety.
