Office CO2 Meters | Commercial Air Quality Monitor | Large Display CO2 Sensor

It measures the same thing over the same 0 to 5000 ppm range. The difference is the display: this one is large format and wall mountable so a whole room can read it, rather than sitting on one desk.

0 to 5000ppm, which covers everything an indoor space produces, including a small sealed room with a lot of people in it.

This store's guidance cites 800 ppm as the point to improve ventilation. We would rather give you the number this listing uses than pretend there is one right answer for every room.

Yes, it is designed for it. That is the main reason to choose this over the portable model.

No. It displays a measurement. It is not a carbon monoxide alarm, not a fire detector and not a substitute for either of those.

At about seated head height on an internal wall, away from the door, the window and any vent. Next to a vent you are measuring the vent.

It tells you the carbon dioxide concentration and nothing more. If you have a genuine workplace air quality concern, that is a matter for a professional assessment rather than a wall meter.

The listing does not state a logging function, so we will not claim one. Treat it as a live display.

Check the instructions supplied with your unit, as we would rather point you at the box than state something this listing does not.

Indoors it is mostly a proxy for ventilation, because people breathe it out. A number that climbs through the afternoon in a closed room is telling you the air is not being changed.

Yes, this one is picked and packed from our own warehouse stock.

Nothing stops you, though the large display is designed for a shared space. For a home office the portable detector is usually the better fit and costs less.

No accuracy tolerance is published on this listing, so we will not quote one. If you need a certified instrument for compliance work, buy a certified instrument.

Follow the instructions in the box. The general rule with CO2 sensors is that time in fresh outdoor air is what resets the baseline.

Delivery is free on orders of £75 or more. Below that it is a flat £25, whatever you order. There is nothing extra added at the end.

5-7 days, after a 24-48 hour handling time. The handling time is the bit before it leaves us, and the 5 to 7 days is the delivery itself.

Not at the moment. Every order goes out on the same tracked service, 5 to 7 days across the UK after the handling time. If you need something by a particular date, email us before you order and we will tell you honestly whether it is possible.

Yes, right across the United Kingdom. We are an online supplier with no shop or showroom, which is how the pricing works.

It is picked and packed from our own warehouse stock. Either way it comes to you with tracking, and you get the tracking number by email once it is on its way.

Yes. You have 14 days to change your mind under the Consumer Contracts Regulations 2013, and we extend that to 15 days under our own policy. Return postage is yours unless the item arrived damaged or faulty, in which case we cover it.

Tell us and we will sort it. Under the Consumer Rights Act 2015 goods have to be of satisfactory quality, fit for purpose and as described, and if they are not that is our problem to fix, not yours to pay for. Email theteam@customersupport.care with a photograph and your order number.

You get an emailed receipt as soon as payment goes through, and a second email with the tracking number once the order ships.

Card payments through our checkout and PayPal. Card details are handled by the payment provider and never stored by us.

Pounds sterling. Every price on this site is the price you pay in £, with no currency conversion at the end.

Yes, `valued-customer` takes 15 percent off your goods at the cart. It applies to the products rather than to the delivery.

No. We are an online supplier with no physical shop or showroom, and that is deliberate: the saving goes into the price rather than into a lease.

Yes, and if you want more than a handful use the wholesale quote page and we will price it properly rather than making you add them to the cart one at a time.

Email theteam@customersupport.care and a person will answer you. We would much rather answer a question first than process a return after.
