Wall-mounted/Tabletop LED Display CO2 Alarm CO2GUARD 10

Wall-mounted/Tabletop LED Display CO2 Alarm CO2GUARD 10

【No calibration required for 5 years】A CO2 meter that displays CO2 concentration with color and sound, ideal for determining ventilation.

● The detection principle recommended by the Ministry of Economy, Trade and Industry is an optical sensor. ● Equipped with automatic CO2 calibration function (automatic correction function). ● High-precision measurement. ● Wall-mounted or portable tabletop placement. ● CO2 concentration displayed in color in stages from 0 to 5000 ppm. ● No maintenance required. ■ The CO2 Guard 10 accurately displays the surrounding carbon dioxide concentration as an indicator of indoor air quality (IAQ). By displaying CO2 levels with an LED, it helps determine the need for ventilation, such as opening windows. Proper ventilation and indoor air quality are very important for maintaining a healthy living and working environment. By maintaining good indoor air quality, the risk of aerosol infections such as the coronavirus can be reduced even in densely populated spaces. Additionally, ventilating based on CO2 levels can significantly reduce energy costs compared to irregular ventilation. For more details, please contact us or refer to the catalog.

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.

What is an oxygen concentration meter?

What is an oxygen concentration meter?

Introducing recommended products based on usage purpose and measurement range!

Here is an introduction on how to choose an oxygen concentration meter. An oxygen concentration meter (O2 meter, Oxygen Analyzer) should be selected based on its intended use and measurement range. Oxygen concentration meters are used to check the concentration of oxygen in medical, personal, and industrial applications. There are various methods for selecting an oxygen concentration meter. Considerations include measurable gases, measurement range, accuracy, installation environment, maintenance, price, and intended use (medical, personal, manufacturing, etc.). Choose the appropriate type and select an oxygen concentration meter that suits the location of use. When selecting an oxygen concentration meter, it is important to consider the following points: - Choose based on the gases that the oxygen concentration meter can measure. - Choose based on the measurement range of the oxygen concentration meter. - Choose based on the measurement accuracy (ppm, ppb, etc.) of the oxygen concentration meter. - Choose between portable or fixed installation for the oxygen concentration meter. - Choose based on the output of the oxygen concentration meter. - Choose based on the installation environment of the oxygen concentration meter. - Choose based on maintenance requirements for the oxygen concentration meter. - Choose based on the price of the oxygen concentration meter. - Choose based on the intended use of the oxygen concentration meter. - Choose a type that fits the application of the oxygen concentration meter. Please check the website below for more information.
