Frequently asked questions
What is the quickest way to reach you?
Email theteam@co2meter.eu.com. Most emails are answered within one business day.
Do you have a phone number?
Yes, and it is on this page. It is an international line, so email is usually faster for order questions.
What are your support hours?
We answer email on business days, normally within one working day.
Where do I ask about a delivery?
Try the track your parcel page first if you have a tracking number. If that does not answer it, email us with the order number.
My tracking has not updated. What now?
Tracking can sit still for a day or two in transit. If it has not moved in several days, email us with the order number and we will chase the carrier.
How do I change my delivery address?
Email us as soon as you can. Once an order has shipped the address cannot be changed.
How do I cancel an order?
Email us as quickly as possible with the order number. Orders can be changed or cancelled until they ship, and most ship within 24 hours.
How do I start a return?
Email theteam@co2meter.eu.com with your order number and what you want to return, and we will tell you how to send it back.
Can I collect from your office?
No. The Amsterdam address is an office, not a warehouse or a collection point.
Do you have a shop I can visit?
No, we are online only.
Can I get advice on which product to buy?
Yes. Tell us the size of the room, what it is used for and what is bothering you, and we will tell you which of ours fits, or that none does.
Can you confirm a specification before I order?
Yes, and please do ask. Where a manufacturer does not publish a figure we will tell you that rather than guess.
Do you answer technical questions after purchase?
Yes, the same address handles those.
What if my product arrives damaged?
Email us with the order number and a photo, and we will sort it out.
What if the wrong item arrives?
Tell us with the order number and we will arrange the correction at our cost.
How do I get a quote for a bulk order?
Use the wholesale quote page rather than the general contact form. It asks the questions we need.
Can you invoice my company?
Yes. Tell us the details the invoice needs to carry.
Do you supply schools?
Yes, regularly. Tell us how many rooms you need to cover and we will quote.
Can you help me choose between the two monitors?
Usually one question settles it: does the whole room need to see the number, or just you. If the room does, that is the wall mounted one.
Do you offer installation or setup?
No, and nothing we sell requires it.
Do you do air quality assessments?
No. We sell instruments rather than services.
Will you tell me if I need a different kind of meter?
Yes. If your problem is dust, smoke or solvents, you need a particulate or VOC meter and we do not sell one.
Can I get a copy of my receipt?
Yes, email us with the order number and we will resend it.
How do I make a complaint?
Email theteam@co2meter.eu.com with the order number. The complaints handling policy page explains the process.
Do you reply to press enquiries?
Yes, use the same address and mark it as a press enquiry.
Do you work with resellers?
Ask us through the wholesale quote page with some detail about your business.
Is there a form I should use instead of email?
The form on this page reaches the same team. Use whichever is easier.
What information should I include?
Your order number if you have one, and what you want to happen. That usually saves a round trip.
Do you answer at weekends?
Occasionally, but plan on a business day reply.
What if I do not get a reply?
Check your spam folder, then email again. We would rather have a duplicate than lose your message.
