Messluft

Messluft, also known as "measuring air" in English, refers to air that is used as a reference medium for calibrating and testing instruments, particularly those measuring flow rates, pressure, or temperature. It is essential that this air possesses known and stable properties to ensure accurate and reliable measurements. Typically, Messluft is carefully conditioned to meet specific standards. This conditioning often involves precise control over its temperature, pressure, and humidity. In some applications, the air may also be filtered to remove particulate matter that could interfere with instrument operation or measurement accuracy. The concept of Messluft is fundamental in metrology, the science of measurement, and is widely employed in industries such as aerospace, automotive, and HVAC (heating, ventilation, and air conditioning) for quality control and performance verification of various devices. Standardized Messluft ensures that instruments calibrated against it will perform consistently and accurately when exposed to similar air conditions in their operational environment.
