Works as well or better than some more expensive brands. Accurate and dependable. Glad I purchased this model. ### ⭐ Bad engineering bad readings. Junk!!! *by R***O on December 19, 2015* After calibrating the unit I am still highly suspicious of its readings. Seems very slow to react to changes in readings. The readings themselves are much higher than the actual levels. It has these obnoxious lights that cannot be turned off. Even when I had taped the lights with black electrical tape the light would then emit from the back of the unit through its ventilation holes. In general this until was poorly thought out and constructed. Wish I would have returned it in time and gotten my money back. There are better meters for the price. I was hoping that this would be a good one but it's not. ### ⭐⭐⭐⭐⭐ A swiss army knife for testing air quality... Needs a builtin battery. *by N***S on March 24, 2015* I did not realize that this device is designed for horticulture and its capabilities far exceeded my requirements. I was looking for a device to monitor C02 levels in my home because, after watching a documentary about the subtle dangers of carbon monoxide, I thought it would be wise to make sure that my home was safe. My home is very well insulated, therefore, it is advised to make sure that ventilation is proper.Right out of the box this device detected that C02 levels in my home were 1910ppm. I was surprised and yet I wasn't because we never open any windows and space heaters/air conditioners are used more frequently than the central air conditioning. According to a quick google search for safe indoor C02 levels, the range should be between 300 to 1000 ppm.I wasn't satisfied with this quick reading so I decided to move the unit around a bit. Unfortunately, since the unit does not have a builtin battery, I couldn't easily place the unit anywhere I wanted. I noticed that the device is powered by an adapter with an output of 6 volt 500mah DC. So I spliced the power connector from the adapter and connected it directly to a 6 volt DC battery. Problem solved, however, do this at your own risk. It is working well for me.When I set the unit up high against my 15 foot ceiling, C02 readings dropped as expected. This was my unscientific method to confirm that this device is actually legit. My next experiments will include reviewing the logs to see how C02 levels are trending throughout my home so that I can identify the source and resolve this issue permanently.Honestly, I didn't expect to get so involved with this project but this device has opened my eyes to the complexities of air quality. Suddenly I'm conscious of humidity levels, C02 concentrations, temperatures, and how these conditions may be affecting my overall well being. It has also made me aware of the need for house plants in order to regulate these conditions.I am thoroughly pleased with this device and I will update this review as my experiments develop. I highly recommend it. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/1661203-apcem-desktop-co2-monitor](https://www.desertcart.hk/products/1661203-apcem-desktop-co2-monitor) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-07-29*
