There is often the question: "Is a CO2 meter mandatory?" This is a relevant and important question, especially in light of the recent pandemic and increasing awareness about air quality in enclosed spaces. Late last year, parliament approved a new law that has now been translated into concrete regulations aimed at improving air quality in various sectors. These new rules will initially apply to the hospitality, sports, and cultural sectors.

CO2 Meters Mandatory in Spaces > 15 m² and Where People Stay Longer Than 15 Minutes
During the COVID-19 pandemic, the use of a CO2 meter, alongside wearing face masks, was already mandatory in the hospitality sector. With the new regulations, this measure is being reintroduced. From now on, any establishment larger than 15 square meters, where people stay for more than 15 minutes, will need a CO2 meter. This measure is a direct response to the lessons learned from the pandemic and serves as preparation for potential future airborne diseases.

Mandatory Air Quality Label
An important addition to the regulations is the mandatory air quality label. Starting January 1, 2025, operators of such establishments must display or publish an air quality label. This label serves as an indication of the measures taken to improve air quality. The label results from a risk analysis and action plan that businesses must develop and implement.

A CO2 meter measures the proportion of CO2 in the air and indicates the air quality of a room, expressed in PPM (parts per million). This tells you when it is necessary to ventilate and clean the room. Aerating rooms ensures that the CO2 content drops and the air quality in the room improves.

Calibration is the comparison of the CO2 meter with a standard to determine its properties.

What is the use of calibration? If the meter deviates in a few years' time, you can recalibrate it. After calibration, your meter will start measuring accurately again. If you take a CO2 meter without a calibration function and it deviates after a few years, you can no longer use it.

1. Place the meter in the middle of (part of) the room, at a height of about 1.5 m from the floor.
2. If mechanical ventilation is present, the meter can be placed at table height.
3. Place the meter as much as possible in the used part of the room.
4. Make sure that the meter is in a safe position so that it cannot fall over or be spilled on.
5. Do not place the sensor next to a door, window or inlet of the ventilation system, nor directly next to people.
6. Do not exhale near the sensor; it will affect the reading.
7. Do not place the meter in direct sunlight or near sources of heat or humidity
8. Do not place the CO2 meter on the ceiling or floor.
9. Provide a meter in every enclosed space
10. CO2 is heavier than air and will therefore tend to sink.
11. Some materials, such as fresh concrete, affect CO2 values.

Tempro delivers solutions that monitor multiple locations simultaneously from an online cloud platform with alerts and reports by email.

If the CO2 meter indicates a value >1200ppm, measures must be taken. This means that your room is not properly ventilated, which can lead to complaints such as headaches, reduced concentration, etc. may occur. If your CO2 meter indicates red, the best thing to do is to ventilate your space as much as possible, for example by opening the windows, until the value has dropped again.

A CO2 meter measures the proportion of CO2 in the air and indicates when you need to ventilate. CO2 meters are recommended in the fight against COVID.

A CO meter measures the amount of deadly CO in the air and indicates incomplete combustion somewhere.

So make no mistake when purchasing a CO2 meter.

At Tempro, we understand that maximizing the efficiency of your datalogger is crucial. Therefore, we would like to share some important tips on managing the battery life of the Efento dataloggers we offer.

Key Factors Affecting Battery Life
The battery life of Efento sensors can be influenced by several settings:

Measurement Interval: The more frequently the sensor collects data, the faster the battery will be consumed.
Synchronization Interval: The frequency with which data is synchronized with your mobile device or cloud also impacts battery consumption.
Signal Strength: The strength of the wireless signal can increase the amount of energy the sensor uses, especially if the signal is weak.
Simulate Battery Life
To help you optimally set your sensor's configurations for maximum battery life, Efento offers a convenient online tool that allows you to simulate the estimated battery life based on your specific usage scenarios. Visit Efento's battery simulation tool to test various configurations and find the best setup for your needs.

Save Battery by Turning Off Bluetooth
After your Efento sensors are programmed, you can save energy by turning off the Bluetooth connection. This significantly extends the battery life. Here’s how you can do it:

Bluetooth Turn-Off Time: You can set the logger to automatically turn off the Bluetooth interface after a period you choose. This means you will not be able to reconnect or change the configuration via your mobile device unless you restart it or remotely enable it from the server. By default, Bluetooth is always on.

Connect to the logger via the Efento mobile application.
Tap on the three dots in the upper right corner.
Select "Power user" -> "BLE turn off time".
These settings are also described in the user manual of the Efento dataloggers. By following these simple steps, you can ensure that your devices last longer and continue to operate efficiently without frequent recharges.

At Tempro, we strive to provide our customers with the best tools and advice to make the most of their monitoring solutions. For more information or support with your Efento dataloggers, please feel free to contact us.

Alarm thermometers and dataloggers serve different purposes.

Alarm thermometers provide immediate alerts when temperatures fall outside set boundaries, which is essential for environments requiring instant responses.

Dataloggers, on the other hand, record and store data over time for later analysis, making them ideal for tracking trends or regulatory compliance. While alarm thermometers initiate immediate action, dataloggers offer a detailed overview of environmental conditions over extended periods.

Dataloggers can also issue alarms, but alarm thermometers cannot log data.
