The Extech CO100 Desktop Indoor Air Quality CO2 Monitor checks for Carbon Dioxide (CO2) concentrations using a maintenance free NDIR (non-dispersive infrared) CO2 sensor. Indoor Air Quality is displayed in ppm with clear Good (0 to 800ppm), Normal (800 to 1200ppm), and Poor (>1200ppm) level indication. The CO100 features a visible and audible CO2 warning alarm for out-of-range levels.

Measurement ranges:

• CO2: 0 to 9,999ppm
• Temperature: 14 to 140°F (-10 to 60°C)
• Humidity: 0.1 to 99.9%RH

Applications include monitoring air quality in:

• schools
• office buildings
• greenhouses
• factories
• hotels
• hospitals
• transportation lines
• anywhere that high levels of carbon dioxide are generated
