The compressed air quality monitor is a comprehensive instrument that integrates multiple detection functions to comprehensively evaluate the quality of compressed air. It can simultaneously detect multiple parameters such as moisture, particulate matter, oil vapor, gas temperature, and pressure in compressed air. It adopts a modular design, and each detection module can work independently or in coordination to improve detection flexibility and accuracy. The outer shell is made of high - strength, corrosion - resistant materials to ensure stable operation in harsh industrial environments. Its advantage lies in its comprehensive detection functions, providing all - around compressed air quality information; intuitive data display for users to quickly understand the situation; and data storage and transmission functions for convenient data management and analysis. It is widely used in industries such as pharmaceuticals, electronics, and automobile manufacturing.
