About CO2 Meter Europe
Instruments that tell you whether a room is ventilated. Delivered across Europe.
What we do
We sell instruments for measuring indoor air, mostly carbon dioxide. It is a narrow range on purpose: two CO2 monitors, ozone machines for odours, and a handful of accessories. No showroom, no installers, no consultancy.
The reason carbon dioxide is worth measuring is mundane. People breathe it out all day, so in a room where fresh air is not arriving the level climbs. That makes one number a decent proxy for ventilation, which is otherwise invisible.
How we work
Everything we sell is self contained. Nothing needs an installer, an electrician or a subscription, and the wall mounted monitor is a self powered unit rather than a wired in device.
Prices are in euro and include everything you pay at checkout. Delivery is free across Europe on orders of €50 or more, and a flat €22 below that.
Not sure which monitor fits your room, or whether we sell the right instrument at all? Email us at theteam@co2meter.eu.com before you buy. If what you need is a particulate or VOC meter we will say so, because that is cheaper for both of us than a return.
What we will not claim
Our monitors measure ventilation, not health. A high carbon dioxide reading means a room needs fresh air; it does not mean anything harmful has been detected, and none of these is a medical or safety device. They do not detect carbon monoxide, which needs its own alarm, and they do not measure dust or solvents. Where a manufacturer publishes no accuracy figure we do not invent one. Our face coverings carry no protective standard and are not certified PPE. We would rather lose an order than sell you the wrong instrument on a promise we cannot evidence.
What we sell
CO2 monitors
A palm sized portable meter reading 400 to 5000 ppm with an audible alarm, and a large wall mounted jumbo display. Both show carbon dioxide, temperature and humidity together.
Ozone machines
Ozone plate machines for breaking down stubborn odours in vehicles and commercial spaces. Used in an empty room and aired out before the space is used again.
Accessories
A cordless handheld fine mist sprayer supplied empty, a UV light wand, a non-contact thermometer and canned oxygen.
Face coverings
A washable vented cloth face covering and a clear reusable face visor. Neither carries a filtration rating or a protective standard.
Frequently asked questions
What do you actually sell?
Carbon dioxide monitors, ozone machines for odour treatment, and a small set of accessories. It is a deliberately narrow range.
What do you not sell?
Particulate meters (nothing here measures PM2.5 or PM10), VOC meters, filter based or HEPA air purifiers, and certified respiratory protective equipment. If that is what you need we will tell you so.
Why focus on carbon dioxide?
Because it is the most useful single number for ventilation. People breathe it out, so the level tracks how much fresh air is reaching a room, which is the thing you can actually do something about.
Which of the two monitors should I buy?
The compact meter if one person is checking rooms or watching a desk or bedroom. The jumbo wall mounted display if a whole room needs to see the number.
Do you publish accuracy figures for the meters?
Only where the manufacturer does, and for the current models they do not. We say that on the product pages rather than inventing a tolerance, and no calibration certificates are available.
Is an ozone machine an air purifier?
No, and it is the most common confusion here. Ozone is a respiratory irritant, so the machine treats an empty room and the space is aired out before anyone goes back in. It is not a filter unit that runs while you sit there.
What does delivery cost?
Free across Europe on orders of €50 or more. Below that it is a flat €22, shown in your basket before you pay.
How long does delivery take?
Orders are handled within 24 to 48 hours, then delivered in 5 to 7 days. Allow about a week in total.
What happens if my order arrives faulty or damaged?
We put it right at no cost to you, with a repair, a replacement or a refund, and we pay the return postage. That applies to everything we sell.
How do I pay?
Credit and debit cards through Stripe, or PayPal. Both go through a secure checkout.
Is there a showroom I can visit?
No. We are online only with no showroom and no collection point, which is part of why the prices stay where they are.
Who am I actually buying from?
The trading name, legal entity, company registration number and registered address are all in the company details on this page. Email us any time and a real person replies.
