CO2 meters

Monitoring air quality has never been easier. Our CO₂ meters accurately measure the level of carbon dioxide in indoor environments and provide real-time alerts when ventilation is needed. This helps you create a healthy and safe working environment in classrooms, offices, hospitality spaces, or laboratories. Tempro’s CO₂ meters combine reliable sensor technology with a clear visual or digital display, and are available in both portable and fixed models.
