The food, beverage industries are required to adhere to strict safety guidelines and regulations to prevent contamination and preserve the high quality of end products. Compliance to safety is so critical that even minor issues can impact produce quality, food safety and result in low yields, unexpected downtime and low-quality end products. Measurement instrumentation helps to prevent issues when growing or processing food and when producing beverages. Reliable and accurate process monitoring and the ability to provide tools are crucial to optimizing the entire production process, from growing the food to preparation, manufacturing, filling, packaging, and storage.

ECN’s measurement device portfolio includes instruments for measuring humidity, temperature, dew point, carbon dioxide (CO2), vaporized hydrogen peroxide, and barometric pressure

Storage and safety 

Many applications require CO2 to be measured either to ensure the quality of the products themselves, or because of environmental requirements related to safety. CO2 needs to be carefully controlled, for example, in vegetable storage facilities, fruit-ripening rooms, frozen foods, food transportation companies, supermarkets, industrial refrigerators, breweries, wineries, logistics hubs and terminals, and storage and transportation of dry ice.

Storage: Optimal storage conditions must be constantly maintained for fresh produce. Proper humidity and CO2 control protects goods against loss of moisture, decay, and aging.

Refrigerated Warehouses: Controlling humidity and temperature levels in refrigerated warehouses reduces frost buildup and condensation, improves energy efficiency, and decreases defrosting costs. Accurate monitoring of moisture levels in the air can reduce unnecessary heating and also reduce energy costs.

Safety: Monitoring CO2 levels is essential to ensure safety of people in fermentation facilities, breweries, wineries, and fruit and vegetable warehouses. Also CO2 refrigerated facilities require measuring CO2 levels in areas where potential refrigerant leaks can occur
