AQMS-09 Online VOCs Gas Monitoring System adopts professional PID photoionization sensor for high-sensitivity VOCs detection. Equipped with heating dehumidification module and LED display, it supports off-grid working and 4G cloud platform real-time data upload. 24-hour unattended monitoring ideal for humid reservoir, coastal and foggy mountainous areas.
Description
AQMS-09 Online VOCs Gas Monitoring System is a high-precision outdoor VOCs environmental monitoring device upgraded with industrial PID photoionization sensor. Different from ordinary TVOC sensors, the PID sensor provides ppb-level ultra-high sensitivity, fast response and wide detection range, accurately capturing trace volatile organic compound pollutants in the air.
Built-in intelligent heating and dehumidification system effectively eliminates condensation and humidity interference, ensuring stable and precise VOCs detection data even in high-humidity, foggy and dew-heavy environments such as reservoirs, coastal zones and mountainous areas. Equipped with outdoor LED display screen, real-time air quality data can be displayed visually on site.
The system supports full off-grid solar power operation and 4G full-network wireless transmission. All VOCs data, gas parameters, dust, noise and meteorological data are automatically uploaded to the cloud platform. Users can remotely view real-time data, historical curves and over-limit alarms, realizing fully unattended 24/7 outdoor environmental monitoring.
Widely used for ecological reservoir environmental protection, coastal industrial park VOCs supervision, mountain hydropower projects, wetland reserves and remote off-grid industrial zones, it provides accurate and compliant VOCs monitoring data for environmental management.
