Datalogging Large Display IAQ Wall Monitor


SKU: 800049 Category:


Poor air quality may cause tiredness, inability to concentrate and even illness (i.e. Sick Building Syndrome). This IAQ Wall Monitor is ideal for monitoring indoor air quality in crowded public spaces with potentially high levels of carbon dioxide such as offices, factories, classrooms, hospitals and hotels. This unit recalls min/max CO2 levels and provides visual alarms for maximum CO2 threshold. The Automatic Baseline Calibration (ABC) and maintenance free NDIR (non-dispersive infrared) CO2 sensor ensure long term accuracy, stability and reliability. Each unit includes an AC adapter and will stand on a desk top or can be wall mounted. The datalogging version also records up to 32,000 data points that can downloaded using the USB cable and software included. 4.5″ x 4.25” x 1″, 6 ounces

Carbon Dioxide Standards

  • 250 to 350 ppm – Background (normal) outdoor air level
  • 350 to 1,000 ppm – Typical level found in occupied spaces with good air exchange
  • 1,000 to 2,000 ppm – Level associated with complaints of drowsiness and poor air
