Best Indoor Air Quality Monitor - Accurate CO2, PM2.5, VOC & Temp/Humidity Detector for Home & Office | Improve Health & Comfort in Bedrooms, Nurseries & Workspaces

Large display continually monitors the 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. Comes with an AC adapter (800059) and will stand on a desk-top or wall mount.

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