FRT AQM312 Gas Monitoring Sensor

WEATHER SENSOR

Model Number : FRT AQM312

Overview

The FRT AQM312 Air Quality Monitoring Station is a multi-parameter air monitoring device independently developed by our company. It can detect environmental gases such as NH₃ (ammonia) and can also integrate modules for monitoring atmospheric temperature, humidity, and pressure. The modular design offers flexible configuration, compact structure, and low cost, making it ideal for networked, high-density, and precision monitoring needs.

Characteristic

Supports station-level calibration with industrial-grade design
Ultra-low power consumption(0.4w); ideal for battery-powered scenarios
Uses PID sensors to accurately detect a wide range of VOCs
Compact size, lightweight, maintenance-free, and easy to install
All-in-one design with excellent scalability for networked monitoring
