CO2 Measuring Devices

Why a CO2 measuring device is important in primary school classrooms: Dangers of excessive CO2 levels

To improve the learning environment in primary school classrooms, it is important to monitor the air quality. Too much carbon dioxide (CO2) in the air can impair pupils' attention and reduce their performance. It is therefore advisable to use a CO2 measuring device in classrooms to regularly monitor the air quality and take appropriate measures if necessary.

• Reduced ability to concentrate
• Reduced cognitive performance
• Headaches
• Increased risk of infection

TimeTEX offers high-quality CO2 measuring devices that are easy to use. A high concentration of CO2 indicates that the class is not getting enough fresh air. It is therefore important to keep an eye on the concentration of CO2 and, if necessary, take measures to improve the indoor air quality.

Schools should therefore use a high-quality CO2 measuring device to create an optimal learning environment for their students and minimise the risk of health problems due to poor indoor air quality. With TimeTEX CO2 meters, teachers have access to accurate information about the air quality in classrooms and can take appropriate action.

TimeTEX meters are of the highest quality and reliable in use. Buy your CO2 measuring device from TimeTEX now and ensure healthy air in the classroom!

Things to know about CO2 measuring devices

How do I measure indoor air?

To measure indoor air quality, including the CO2 concentration, you need a CO2 measuring device. These devices use sensors to measure the CO2 content in the air. To obtain the most accurate readings possible, it is advisable to place the CO2 meter at table height in a suitable location. Care should be taken to ensure that the device is not in the immediate vicinity of people, as this can lead to unreliable results due to inhalation. Furthermore, it is important to place the measuring device at least 1.5 meters away from windows or doors to avoid falsified results.

It is also important to ensure that the meter is properly calibrated and regularly maintained to ensure accurate and reliable measurements.

How good are CO2 measuring devices?

Modern CO2 measuring devices have improved considerably in recent years and offer a high level of accuracy and reliability when measuring CO2 concentrations. They are able to provide fast and precise readings and often have additional functions such as displaying temperature, humidity and air quality.

What does a good CO2 meter cost?

The price of a good CO2 meter can vary depending on the brand, functions and accuracy. In general, however, it can be said that high-quality CO2 meters range in price from around 100 to 500 euros. There are also cheaper models, but their accuracy and reliability may be compromised.

How much CO2 is allowed in a room?

The maximum permissible CO2 concentration indoors is often set by guidelines and standards. The Federal Environment Agency classifies a CO2 concentration below 1000 ppm as harmless. This value is regarded as an indicator of good indoor air quality. A CO2 level between 1000 and 2000 ppm is classified as conspicuous and concentrations above 2000 ppm are considered unacceptable. Higher concentrations may indicate inadequate ventilation or a high number of people and can lead to a deterioration in indoor air quality. It is important to regularly monitor rooms for CO2 concentrations and take appropriate ventilation measures to prevent deterioration of indoor air quality and maintain a healthy and comfortable indoor environment in which children can learn productively.

Air quality measuring device CO2 traffic light

The innovative CO2 traffic light in the form of a stylish pillar is a real eye-catcher and, thanks to the traffic light system in the colours green, yellow and red, indicates at a glance whether there is a need for action or not. Thanks to its size and the 360° illuminated bands, the corresponding colour is clearly visible from any position in the classroom. As each colour has its own light band, the colours can be clearly identified by their position in the column, even for people with colour blindness!

The colour levels are based on the specifications of the Federal Environment Agency. Up to a carbon dioxide level of 1,000 ppm, the traffic light is green (everything is OK), then yellow up to 2,000 ppm (from 1,000 ppm, the Federal Environment Agency recommends ventilation). From 2,000 ppm, the red light switches on (immediate ventilation is urgently required) and flashes from 3,000 ppm until the traffic light turns green again, i.e. a good indoor climate has been achieved.

The CO2 traffic light air quality measuring device helps to reduce the CO2 concentration in every classroom with a room size of up to 100 m² in order to maintain the children's concentration and minimise the risk of infection.

The CO2 traffic light meter is equipped with a powerful, calibrated sensor for measuring CO2 and is supplied with a power supply unit. It is easy to connect and calibrates itself automatically within three minutes. It then indicates the current CO2 concentration level by means of a coloured light strip.

A wall mounting bracket is available to match the CO2 traffic light, allowing the traffic light to be practically mounted on a room wall. This enables optimum positioning of the CO2 traffic light measuring device for schools at the point where it can be best recognised from all points in the room. The holes in the metal bracket allow for quick installation.

CO2 "Plus" air quality meter

Experts agree: reducing the concentration of CO2 indoors can minimise the risk of infection from harmful aerosols. Sufficient fresh air is essential to minimise the transmission of pathogens.

Our innovative CO2 "Plus" air quality meter is perfect for use in classrooms to maintain student concentration and reduce the risk of infection. It continuously monitors the CO2 concentration, room temperature and humidity and shows the values on a display in traffic light colours. This allows you to recognise at a glance whether everything is in the green zone or whether there is a need for action.

Fresh air is not only important for health, but also for pupils' performance. Timely ventilation can prevent headaches, dizziness and tiredness. Our CO2 measuring device not only displays the current values, but also a history of the last 24 hours. This allows you to ensure that the air quality in your classroom is optimal at all times.

The display of this innovative measuring device can fulfil an important signalling function: It changes the backlight from green to yellow to red depending on the amount of CO2 in the air. This means that you can immediately see how polluted the air in your classroom or office is and can optimise the room climate through targeted ventilation.

It is also possible for the display to only light up when a certain level of CO2 is exceeded (alarm function), to be permanently illuminated in a single colour or for the lighting to be switched off completely. This means that your students are not distracted during exams, for example, and the indoor air quality can still be monitored.

In addition to improving indoor air quality, this measuring device also promotes the health of your students and your own. Stuffy, stale air contains more aerosols and therefore increases the risk of viral infections. However, by regularly ventilating and supplying fresh air, you can defy any season and create a healthy indoor climate.

This CO2 measuring device is a useful tool that comes with a practical USB cable. Thanks to this, you can easily connect it to a laptop or power supply. And best of all, you can even use it as a mobile device by simply connecting it to a power bank. This means you can measure the CO2 content indoors and outdoors and show it to your students anytime, anywhere.

As well as being easy to use, the device also ensures a stable hold. Thanks to its compact size, it is also unobtrusive and does not cause any unnecessary distractions.
