The AQM-421 Professional 5in1 Indoor Air Quality Monitor is a cutting-edge solution designed to ensure a healthier living environment in your home, office, or any indoor space. This all-in-one device accurately measures five critical air quality parameters: Carbon Monoxide (CO), Carbon Dioxide (CO2), Total Volatile Organic Compounds (TVOC), Humidity, and Temperature. With its high precision NDIR sensor, you can trust in the reliability of the data provided, allowing for informed decisions to improve indoor air quality.

Advanced Features and Specifications

The AQM-421 is equipped with a large, clear LCD display that makes it easy to read your air quality measurements at a glance. Its professional Electrochemical Infrared NDIR sensor ensures accurate readings, while the selectable temperature unit (°C/°F) offers flexibility. The device features power-saving mode, which dims the screen after 1 hour of continuous usage, ensuring long-lasting battery life. Key specifications include a test range of 0-1000PPM for CO, 400-5000PPM for CO2, and 0.000-5.000mg/m3 for TVOC. The device also offers a range of temperature and humidity measurements, with accuracy levels up to ±5% for humidity and ±1.5°C for temperature.

Its compact and portable design makes it perfect for use in homes, offices, schools, and grow tents. The device's air vent ensures stable airflow, and the CO and CO2 concentration indicators provide immediate visual feedback, alerting you to potential hazards.
