Outdoor air quality monitoring system TRACK+ RAIL

CO2relative humiditytemperature

Product overview
TRACK+ RAIL is an air quality monitoring station designed for underground railway stations and tunnels. It measures temperature, humidity, fine particles (PM1, PM2.5, PM5), atmospheric pressure, CO2 and can be extended with additional sensors (O3, NO2, etc.) via modular BLOCK slots. The station is optimized for underground railway tunnels and includes design elements for reliable aerosol sampling and pest protection.

Key features

• Multi-connectivity: LoRaWAN or 4G LTE (multi-operator SIM supplied)
• Optimized for underground railway tunnels (URTs) with a fine-particle sensor designed for tunnel conditions
• Multi-sensor modularity with up to 5 BLOCK slots for adding sensors or measurement modules
• Local data logger (built-in SD card storing up to 20 years of data)
• Enhanced cybersecurity: end-to-end double AES128 encryption
• Clear 360° aerosol sampling system for unbiased particulate sampling
• Integrated insect/pest protection grille
• Reduced maintenance: no maintenance required for the fine particle sensor for 1 year in standard configuration
• Simple installation and simplified on-site maintenance (replace wearing parts without removing station from mount)

Sensors & measurements

• Particulate Matter (PM1, PM2.5, PM5): continuous or intermittent mass measurement on 3 channels; mass measurement range 0 to 1,000 µg/m3; repeatability error <3; linearity error <5; resolution 1 µg/m3
• Atmospheric Pressure: resolution 1 hPa; accuracy ±2.5 hPa; measurement range 300–1100 hPa
• Temperature: resolution 0.1°C; accuracy ±0.3°C; measurement range -30°C to +70°C
• Humidity: resolution 0.5% r.H.; accuracy ±2% r.H.; measuring range 0–100% r.H.
• CO2: resolution 1 ppm; accuracy 30 ppm or ±3%; measuring range 0–10,000 ppm

Connectivity & data

• LoRaWAN and cellular (4G LTE) options; device supplied with a multi-operator SIM for wide coverage
• Open and secure LoRaWAN protocol for plug-and-play integration with monitoring software of choice
• Data recovery via 4G network (CELLULAR option) and 5 years' access to NAVIXIS web platform when configured
• NAVIXIS platform: visualization of measurements, curves, CSV exports, API/webhook connectivity, configurable alerts, fleet management
• Local data logging via SD card (up to 20 years storage)

Installation & power supply

• Mounting: wall-mounted or pole-mounted (pole fixing kit supports diameters 60–400 mm)
• Power supply options: AC (110V–230V), DC (5V–35V), LFP lithium battery (100 Wh), optional solar power kit (autonomous supply with high-capacity battery)
• Battery operation: station can run up to ~3 days without mains; automatic recharge when mains restored

Maintenance & durability

• Reduced maintenance for fine particle sensor (no maintenance for 1 year in standard configuration)
• Replacement of wearing parts (fine particle sensor, battery) simplified and possible without removing station from mount
• Robust sampling system and pest protection grille to preserve measurement reliability

Kit contents
