The principle of an oxygen concentration meter.

Principle of Galvanic Battery Type/Zirconia Type Oxygen Concentration Meter

In Tekune Measurement, we handle two types of oxygen concentration meters based on the principles of galvanic cell and zirconia methods. 〇 Galvanic Cell Type The lead anode performs an oxidation reaction, assisting the reduction reaction at the cathode. It behaves as if combustion is occurring at the anode due to oxygen, generating current, which is why it is also called a fuel cell type. PPM models: 2010BX, 2001RS, 2001LC, 1000RS % models: 210BX, Oxtron, 201RS, 1100BE, 201LC 〇 Zirconia Type It compares an unknown process gas with a known reference gas using the Nernst equation. The sensor measures the electromotive force to determine the oxygen concentration. Examples of PPM models: 4100, 7100, etc. Examples of % models: 111, 5100, etc. For more details on the principles of oxygen concentration measurement, please refer to the URL below.

Wall-mounted/Desktop LED Display CO2 Alarm CO2GUARD 10

【No calibration needed 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. Maintaining good indoor air quality can reduce the risk of aerosol infections, such as the coronavirus, 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.

CO2 (carbon dioxide) sensor module

Achieving high gas selectivity and high precision with a single light source dual-wavelength NDIR (non-dispersive infrared absorption) method!

We introduce the 'CO2 (carbon dioxide) sensor module,' which has achieved a lifespan of over 10 years without calibration through the optimization of sensing intervals. By utilizing the fact that the infrared absorption characteristics differ depending on the type of gas, we have adopted a method that measures two wavelengths: the CO2 absorption wavelength and a reference wavelength. This module can be used for applications such as monitoring ventilation conditions, confirming the presence of people and animals, managing growth environments through the photosynthesis-promoting effects on plants like crops, and checking for the presence and freshness of vegetables in refrigerators. 【Features】 ■ Widely used for air quality monitoring ■ Adopts a method that measures two wavelengths: the CO2 absorption wavelength and a reference wavelength ■ Achieves high CO2 selectivity and high precision ■ Achieves a lifespan of over 10 years without calibration through the optimization of sensing intervals *For more details, please refer to the related links or feel free to contact us.

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 the gases that can be measured, measurement range, accuracy, installation environment, maintenance, price, and intended use (medical, personal, manufacturing, etc.). Choose the appropriate type to select an oxygen concentration meter that fits the usage location. 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 price for the oxygen concentration meter. - Choose based on the intended use of the oxygen concentration meter. - Choose a type suitable for the application of the oxygen concentration meter.
