relative humiditytemperatureNO2

Overview
BLOCK is a modular air quality measurement cartridge designed to extend and customise TRACK+ family monitoring stations. Deploy selectable pollutant cartridges on existing TRACK+ or TRACK+ RAIL stations to match operational monitoring needs.

Key features

• Modular and scalable architecture compatible with TRACK+ and TRACK+ RAIL stations.
• Each station supports up to 5 BLOCK slots for adding sensors or measurement cartridges.
• Factory calibration and rigorous sensor characterisation ensure reliable, comparable data with repeatable measurement performance.
• Real-time temperature and humidity compensation stabilises readings and limits sensor drift across weather conditions.
• Plug-and-play cartridges and remote monitoring simplify maintenance and reduce field interventions, costs and downtime.

Measured pollutants / Supported sensors

• Ozone (O3)
• Nitrogen Dioxide (NO2)
• Additional pollutant cartridges selectable according to operational requirements

Applications & Integration

• Enhances outdoor air quality monitoring networks by enabling rapid integration of new sensors and feature upgrades.
• Facilitates flexible deployment strategies and scalable monitoring fleets for urban, industrial or transport-related sites.
