Indoor CO₂ Meter

CO₂ Meter with Alarm Function – Accurate Indoor Air Quality Monitoring

The Newentor CO₂ meter is designed for continuous monitoring of carbon dioxide levels in indoor environments. It supports controlled ventilation and helps maintain a healthy indoor climate. Especially in schools, offices, homes, and shared indoor spaces, the device enables quick assessment of air quality and timely action when CO₂ concentrations increase.

The display features four color-coded CO₂ concentration levels that clearly indicate the current indoor air quality. In addition, both visual and audible alarms notify users when predefined CO₂ thresholds are exceeded. This allows you to see at a glance when ventilation is required and when air quality has returned to an optimal level.

High-Precision NDIR Sensor and Reliable Measurements

The device is equipped with a high-precision NDIR sensor (Sensirion SCD41), manufactured in Switzerland. This sensor provides reliable CO₂ measurements in a range from 400 to 5,000 ppm with an accuracy of ±40 ppm. As a result, the meter is also suitable for applications requiring stable and reproducible measurements.

In addition to CO₂ concentration, the device measures temperature and relative humidity. An integrated memory function displays the minimum and maximum values recorded over the previous 24 hours, providing users with a clear overview of indoor climate trends.

Flexible Operation and Versatile Applications

The CO₂ meter can be powered either by batteries or via USB. When connected via USB, measurement values are updated automatically at short intervals. In battery mode, manual real-time measurements are available. A low-battery indicator provides timely notification when battery replacement is required.

Thanks to its compact design and easy-to-read display, the device is suitable for use in:

• Schools and daycare centers

• Offices and meeting rooms

• Living rooms and bedrooms

• Motorhomes and temporary living spaces

The CO₂ meter is a practical solution for monitoring indoor air quality in both residential and professional environments.
