KEY FEATURES

• Simple, fast and precise measurement of CO₂ concentration
• Audible alarm sounds if a limit value is exceeded
• Fast in-app configuration, graph history, second screen and measurement data memory in the testo Smart App
• High reproducibility of measurement results due to long-term stable infrared sensor technology

The Testo Digital CO₂ Measuring Instrument delivers a highly effective and space-saving diagnostic framework for supervising indoor climate ventilation loops, evaluating office air health standards, and executing fast facility comfort checks. Standard gas detection meters often struggle with sensor baseline drift errors or complicated hardware menus that delay testing workflows; by utilizing advanced long-term stable infrared technology alongside a direct smart interface, this unit guarantees excellent field tracking repeatability. Technicians can configure custom alert limits, manage running parameter charts, and finalize compliance logs directly from a smartphone screen, ensuring safe, professional data recording across multi-room site inspections.

ADDITIONAL FEATURES

• Integrated audible warning alarm sounds promptly when custom carbon dioxide threshold limits are exceeded
• Robust ABS, PC, and TPE housing provides excellent durability for demanding field applications
• High-resolution 1 ppm display resolution enables precise monitoring of changing indoor air quality conditions
• Protective transport bag safeguards the instrument during storage and transportation
• Powered by three AA batteries, providing up to 30 hours of continuous operation

APPLICATIONS

• Perfectly optimized for indoor air quality assessments, carbon dioxide concentration monitoring, workplace ventilation verification, building compliance inspections, and smartphone-supported environmental data logging across offices, classrooms, healthcare facilities, and commercial buildings.
