Extech CO270 Offers

The air inside buildings can significantly affect our health, comfort, and productivity; thus, monitoring humidity, temperature, and airflow helps protect health, boost productivity, optimize HVAC/R systems, meet regulations, and improve comfort. The CO270 is a battery‑operated, handheld CO2 meter designed primarily for indoor air quality (IAQ) diagnostics.

Features

  • Programmable buzzer features to alert when set threshold is exceeded
  • CO2 manual calibration feature
  • Recall peak and average value over the last 24-hour period
  • Maintenance free NDIR (non-dispersive infrared) CO2 sensor
  • Includes anti-theft and anti-modification features
  • Typical battery life 6 months or 1 year in ECO mode

Applications

  • Indoor environment health checks: Ensuring CO2 levels remain below recommended thresholds (1000 ppm per ASHRAE for ventilation comfort)
  • HVAC/R commissioning: Quick verification that fresh air intake is sufficient
  • Educational facilities, offices, meeting spaces, and greenhouses: Monitoring air quality to avoid drowsiness or poor cognitive performance due to elevated CO2
  • Portable IAQ screening: Field teams can check multiple spaces without having to plug in or install the device
