BZ25 CO2 Meter Trotec - Air Quality

CO2 Indicator BZ25 - TROTEC

The BZ25 CO2 indicator ensures reliable and lasting measurement of carbon dioxide concentrations in your indoor air. Thanks to its advanced NDIR sensor technology, this device guarantees constant monitoring of ambient air quality.

Why monitor indoor air?

We spend more than 90% of our time in enclosed spaces. Modern thermal insulation, while beneficial for energy efficiency, can unfortunately trap various pollutants. High levels of CO2 cause fatigue, lack of concentration, and other health discomforts, with a particularly marked impact on children and immunocompromised individuals.

Application areas

The BZ25 integrates perfectly into single-family homes, office spaces, classrooms, childcare facilities, and industrial sites. Beyond carbon dioxide, it also measures temperature and humidity, with all data displayed on a particularly readable screen.

Key features

Configurable CO2 alert: set a custom audible signal as soon as a critical threshold is reached

Versatile LCD screen: view date, time, and air quality via a graphical indicator of concentrations

Smart calibration

The automatic calibration system adjusts the reference to 400 ppm (0.04%), the value corresponding to pure outdoor air. A dedicated algorithm analyzes the lowest measurements over several days to maintain long-term accuracy. Note: this automatic calibration mode is not suitable for permanently occupied premises or environments with high CO2 emissions such as agricultural greenhouses.
