The principle of the CO2 meter (carbon dioxide concentration meter).

The principle of the CO2 meter (carbon dioxide concentration meter).

The detection principle recommended by the Ministry of Economy, Trade and Industry for CO2 measuring devices is an optical sensor. It comes with an automatic calibration function (automatic correction function) and excellent long-term stability.

We have adopted a unique automatic calibration method (double beam NDIR method). As a result, it excels in long-term stability and maintainability, with a very low annual drift of only 20 ppm/year. Its reliability is proven not only through rigorous testing but also by its market share in Europe. Please choose from the duct-mounted EE850, the wall-mounted EE800, or the agricultural EE820. You can also select options for concentration scaling and output. For more details on CO2 meters in general, please visit the URL below.

Railway CO2 meter, temperature and humidity meter, humidity meter, dew point meter, carbon dioxide meter.

CO2 meter for passenger car ventilation purposes, temperature and humidity, dew point meter.

Due to the spread of the coronavirus (Covid-19), the importance of ventilation in passenger cars is being emphasized. Temperature and humidity measurements in the passenger cabin are being conducted using the simple EE-060/EE-061 temperature and humidity meters, and ventilation management is progressing with CO2 meters (carbon dioxide meters). In particular, we sell a CO2 meter specifically for passenger cars, the EE8915, which has a proven track record. Additionally, we recommend the TE-660 dew point transmitter for train-mounted dew point measurement.
