Did you know… 10 facts about carbon dioxide and carbon dioxide monitors
Although carbon dioxide (CO2) monitors aren’t very exciting or pleasing to the eye, here at Gem Scientific, we are committed to keeping our customers safe from potentially fatal gas leaks.
Here are ten facts about carbon dioxide…
1: CO2 IS KNOWN DIFFERENTLY DEPENDING ON WHERE IN THE WORLD YOU ARE
For example, it is known as ‘koldioxid’ in Sweden, ‘二氧化碳’ in Chinese and ‘süsinikdioksiid’ in Estonian.
In Dutch, it is known simply as… carbon dioxide.
2: CO2 EXISTS NATURALLY IN THE ATMOSPHERE
Carbon dioxide is present in the air we breathe every day, although concentrations are so minuscule (around 0.04%), monitoring is not needed everywhere. However, it is imperative to measure levels of carbon dioxide in an industrial environment, especially in confined spaces as levels can quickly increase, without the correct ventilation
3: CO2 LEVELS RISE IN CROWDED ROOMS
We breathe in oxygen and breathe out carbon dioxide, which means that CO2 levels in a room can rise over the course of the day. When we’ve attended exhibitions in the past, we’ve monitored levels of CO2 for this very reason!
Although the rise in CO2 will not put you in danger, it could make you feel more tired and lethargic. The best thing to do is to keep the room ventilated with plenty of fresh air.
4: CARBON DIOXIDE HAS NO TASTE, COLOUR OR SMELL
Monitoring CO2 is very important because it cannot be seen, tasted and has no odour, which makes it hard to know when levels of it increase.
5: CO2 CAN BE USED TO INCREASE GROWTH OF FLOWERS, FRUIT AND VEGETABLES
Plants use sunlight, carbon dioxide and water to generate food in a process called photosynthesis. Greenhouse owners often increase the amount of carbon dioxide in the atmosphere in order to promote growth, although this is a balancing act as if carbon dioxide levels are too high, it can damage the crops.
We’ve developed CO2 monitors which can automatically shut down the CO2 supply to the greenhouse if levels rise beyond an acceptable standard.
6: CARBON DIOXIDE AND CARBON MONOXIDE ARE TWO VERY DIFFERENT THINGS
We’ve noticed some people get carbon dioxide and carbon monoxide confused; if you do a search for ‘carbon dioxide monitor’ a lot of the top results are for carbon monoxide, which is worrying.
Although both of these gases have no taste or smell, CO2 occurs naturally in the atmosphere, whilst carbon monoxide does not. CO2 is heavier than air and gathers nearer the ground, whilst carbon monoxide is lighter than air and gathers higher up.
7: DRY ICE IS MADE OF CO2
Dry ice, which is used in refrigeration, special effects and cleaning, is made of solid carbon dioxide. This means it must be treated in the same way as CO2 gas and not used in confined spaces.
8: CO2 IS USED TO DISPENSE BEER
If you go to a pub or a bar, chances are that they do have a CO2 monitor in the back of the facility or in their cellar (or they should have). This is because CO2 (or ‘dispense gas’ as it is commonly known in the beverage industry) is used to add the bubbles to beer as well as push it from the keg to your glass.
9: CARBON DIOXIDE CAN BE USED TO KEEP HOME FURNISHINGS CLEAN
Did you know an American University has conducted research where the CO2 vapour is used to freeze home furnishings? This process removes allergy-causing substances and kills dust mites, reducing asthma symptoms.
10: CO2 CAN BE USED TO PUT OUT FIRES
Carbon dioxide is used in some fire extinguishers. It works by removing the oxygen that the fire needs to burn, plus it is cheap and widely available.
However, it can be dangerous if used in an enclosed space as not only can it take oxygen away from the fire, it can take oxygen away from the atmosphere and you too.
Analox AX60+ Wall Mountable CO2 Detector
The Analox AX60+ is a wall-mountable multi-gas monitor for detecting CO2 with an option for monitoring oxygen. The CO2 sensor is set by default to trigger a low-level alarm at 1.5% CO2, an evacuation alarm at 3% CO2 and a time-weighted average alarm of 0.5% CO2 measured over eight hours. Each alarm unit is equipped to provide an early warning including an audible sounder and a high-intensity LED strobe light – perfect for warning of danger in noisy environments.
