The Nexelec BLOCK is a plug-and-play air quality measurement cartridge that adds ozone (O3), nitrogen dioxide (NO2), or nitric oxide (NO) sensing to TRACK+ and TRACK+ RAIL air quality stations. Up to 5 BLOCK cartridges can be installed per station, allowing the pollutant mix to be tailored to the deployment without replacing the station itself.

BLOCK cartridges are factory-calibrated and include real-time compensation for temperature and humidity effects to ensure stable, reliable measurements across all weather conditions. Replacement is tool-free and can be done on site without removing the station from its mount.

Key Features

  • Modular gas sensing for TRACK+ stations: Each TRACK+ or TRACK+ RAIL station accepts up to 5 BLOCK cartridges simultaneously. Choose ozone, NO2, or a mix — and redeploy or swap cartridges as monitoring needs change.
  • Available variants: BLOCK O3 (ozone, X961LT), BLOCK NO2 (nitrogen dioxide, X962LT), and BLOCK NO (nitric oxide, X963LT). All variants share the same dimensions, performance spec, and lifespan.
  • Factory calibration: Each cartridge is factory-calibrated and characterized for guaranteed accuracy and repeatability across units and deployments.
  • Real-time environmental compensation: On-board compensation for temperature and humidity effects stabilizes measurements and limits drift in variable outdoor conditions.
  • Plug-and-play installation: Tool-free field installation and replacement. Cartridges slot directly into the BLOCK bays on the host station. No wiring, no configuration required.
  • Simplified maintenance: Replaceable cartridges with a defined 2-year lifespan, combined with remote monitoring via the NAVIXIS platform, reduce field interventions, costs, and downtime.
  • Compact and lightweight: 48 × 42 × 39 mm, 50 g — fits entirely within the TRACK+ station enclosure.

Applications

  • Adding ozone, NO2, or nitric oxide monitoring to existing TRACK+ outdoor air quality stations
  • Expanding TRACK+ RAIL underground railway stations with gas pollutant sensing
  • Urban air quality monitoring networks requiring flexible pollutant coverage
  • Industrial perimeter monitoring for ozone and nitrogen dioxide emissions
  • Regulatory compliance monitoring requiring multi-pollutant measurement

Important Notes

  • BLOCK cartridges require a TRACK+ (X950LS) or TRACK+ RAIL (X951LS) host station. They do not operate independently and have no wireless connectivity of their own.
  • Each station accepts a maximum of 5 BLOCK cartridges. Cartridges are ordered separately from the host station.
  • Cartridge lifespan is 2 years. Plan for scheduled replacement as part of ongoing station maintenance.
  • Operating humidity range is 15–90% RH — confirm suitability for high-humidity deployment sites.
