Description

The TES-5321A / TES-5322A PM2.5 Air Quality Monitor is a portable indoor air quality monitoring device designed to deliver direct, real-time readings without the need for internet connectivity or mobile applications. This stand-alone monitor allows users to easily assess air quality conditions anytime and anywhere through its clear LCD display and intuitive interface.

Both models provide accurate measurement of PM2.5 particulate matter, along with ambient temperature and relative humidity, enabling comprehensive indoor air quality evaluation. The TES-5322A further enhances monitoring capability by supporting VOC (Volatile Organic Compounds) detection, making it suitable for environments where chemical emissions and indoor pollutants are a concern.

Equipped with color LED air quality indicators, the monitor offers instant visual feedback on air conditions, while the alarm output function alerts users when air quality exceeds preset thresholds. The built-in data logging capability supports continuous monitoring and trend analysis, making it useful for both short-term assessments and long-term environmental evaluation. Designed for convenience and versatility, the TES-5321A / TES-5322A is ideal for use in homes, offices, schools, healthcare facilities, and industrial environments, providing reliable air quality information to support health, safety, and environmental management.
