4. Application for pharmaceutical industry
For pharmaceutical industry, environmental control, especially in humidity, can directly affect the process lines in many ways. Compressed air can be used for a wide range of applications in the pharmaceutical industry, such as raw material transport, processing equipment, and cleaning. Unchecked dew point level in compressed air may have an undesirable effect on chemical stability and physical stability. Dew point meters can play one of crucial roles on moisture measure of compressed air. Moisture can result in a number of potential risks, such as equipment failure, condensation in process lines and the potential for microbial formation. In the pharmaceutical industry, it cannot use dirty air or humid air for medicinal applications. For instance, bulk solid and powder conveyors used for moving product rely on clean and dry air in order to prevent contamination from being transferred directly to the products. So, the method of moving product is important. During production, storage or transportation, if the moving is contaminated by moisture, it is easy for pharmaceutical products to become damaged. Wet condition is a good breeding ground for bacteria and mold, which you do not want anywhere near pharmaceutical production. That is why it is important to make sure you monitor your dew point when operating. Using dew point sensors can make your dew point control as simple as possible.

5. Benefits of monitoring dew point
• Avoid the growth of microorganism
• Prevent the risk of contamination
• Ensure higher product purity
• Reduce equipment damage
• Reduce unnecessary energy costs
