Description

Large display continually monitors primary IAQ (Indoor Air Quality) parameters: Air Temperature, RH, CO2

Poor air quality may cause tiredness, inability to concentrate, and even illness (i.e., Sick Building Syndrome). This instrument is ideal for monitoring indoor air quality in crowded public spaces with potentially high levels of CO2 (carbon dioxide) such as offices, factories, classrooms, hospitals and hotels. Recalls min/max CO2 levels and provides visual alarms for maximum CO2 threshold. Automatic Baseline Calibration (ABC) and maintenance free NDIR (non-dispersive infrared) CO2 sensor ensure long-term accuracy, stability and reliability. Records up to 32,000 data points that can be downloaded to your computer using the USB cable included. Comes with an AC adaptor, USB cable, software, and will stand on a desk-top or wall mount.

Dimensions: 4½" × 4¼" × 1" (108 × 115 × 25 mm)

CO2 Levels	Exposure Effects
250-350 ppm	Background (normal) outdoor air level.
350-1,000 ppm	Typical level found in occupied spaces with good air exchange.
1,000-2,000 ppm	Level associated with complaints of drowsiness and poor air.
2,000-5,000 ppm	Level associated with headaches, sleepiness, and stagnant, stale, stuffy air. Poor concentration, loss of attention, increased heart rate and slight nausea may also be present.
> 5,000 ppm	Exposure may lead to serious oxygen deprivation resulting in permanent braindamage, coma and even death.
