Check indoor air with confidence. Extech CO270 Battery Operated Air Quality CO2 Meter measures CO2, temperature, humidity and dew point in one device. It runs on AAA batteries so you can place it wherever you need, and ECO mode extends the life of those batteries. You work without cables, and you keep your workspace tidy.
Fast checks with clear alerts
Set the alarm to your limit, and the buzzer warns when air quality falls. You see trends with peak and average values captured across the last twenty four hours. You act fast with clear feedback and you keep rooms safe for staff and visitors.
Practical design for shared spaces
Use the anti-theft features in public areas, and prevent tampering with the anti-modification safeguards. Install the hanging screw to secure the unit and reduce downtime from loss. Power remains simple with replaceable AAA batteries, and setup takes minutes with the quick start guide.
Field accuracy stays consistent because you can perform manual CO2 calibration when needed. The instrument meets EN 61326-1 and IEC 61000-4 for electromagnetic compatibility, and that supports use in commercial settings. The two year warranty gives peace of mind, and the support trail stays clear with global GTIN codes.
