Over 90% of manufacturing facilities world-wide use compressed air as part of their manufacturing process. However, this powerful utility is not without its problems, in the form of compressed air contamination. It is therefore common practice to install compressed air filters as part of a “purification system” to ensure contaminants are reduced and the system operates in a safe, efficient and cost effective manner.
In the food and beverage packaging industry, authenticity is essential. Consumers need to know that the foods they’re purchasing consist of the things listed on their labels, as food allergies and expired foods can cause serious illness and possibly death. Since both public health and consumer satisfaction depend so heavily on product integrity, the food and beverage packaging industry is highly regulated.

Occasionally questions come up with regard to calibration of Watlow controllers. This paper will attempt to address some of the more common questions on this subject. Many people want to jump in right away and begin performing a calibration procedure before verification. Before you would attempt to calibrate a Watlow controller, verify that the controller is in need of calibration. If you verify that readings of the controller first, you may not have to go through the more involved process of changing the calibration settings.
