INKBIRDPLUS Portable CO2 Detector, Mini Indoor CO2 Monitor, NDIR Sensor with Full Color LCD, for Home, Office, Travel (PTH-10C)

I’d be thrilled to share my experience with the INKBIRDPLUS Portable CO2 Detector, Mini Indoor CO2 Monitor, NDIR Sensor with Full Color LCD, for Home, Office, and Travel (PTH-10C). From the moment I unboxed it, I knew this device was something special. Let me take you through why I am so impressed with this portable CO2 detector. First off, the build quality is outstanding. The device has a sleek and modern design, which is both functional and aesthetically pleasing. It's compact enough to fit in your pocket or hang around your neck with the included lanyard, making it perfect for on-the-go use. The lightweight feel makes it easy to carry around without any hassle, whether you're at home, in the office, or traveling to different locations. The CO2 detection capabilities are what truly set this device apart. Utilizing an advanced NDIR sensor, it delivers highly accurate readings of carbon dioxide levels, a critical factor in maintaining a healthy indoor environment. The sensor's infrared technology ensures strong anti-interference and excellent stability, providing consistent and reliable data. This is crucial, especially for those who are conscious of indoor air quality or have health concerns related to air pollution. The full-color LCD display is vibrant and easy to read, offering clear information at a glance. I appreciate that it changes color based on CO2 concentration levels: green for safe, yellow for moderate, and red for high levels of CO2. This color-coded system is incredibly intuitive, allowing you to quickly assess the air quality without needing to read detailed numbers. It's a thoughtful design choice that adds to the user-friendly nature of the device. Another standout feature is the customizable alert system. The detector emits an audible alarm when CO2 levels exceed 1500ppm, but you can also set your own alert values based on your specific needs. This flexibility is a great addition, as it allows you to tailor the device to your environment and sensitivity levels. The portability and battery life are also impressive. With a built-in 1000mAh lithium battery, you can get up to 72 hours of use on a single charge. It only takes about 3 hours to fully recharge, and the included 2-meter charging cable gives you plenty of flexibility when finding a charging spot. The ECO mode feature, which kicks in after 5 minutes of inactivity, helps conserve battery life when you're not actively using the device. Setting up the CO2 detector is a breeze, but it's worth noting that you should calibrate it in an open and uninhabited environment for the first use to ensure accurate readings. This step is simple to do and ensures that your device is providing the most precise data possible. Overall, the INKBIRDPLUS Portable CO2 Detector is an exceptional product for anyone looking to monitor indoor air quality. It's versatile, reliable, and easy to use, with a design that fits seamlessly into any setting. Whether you're at home, in the office, or on the road, this CO2 monitor is a fantastic companion to ensure you're breathing clean and safe air. I highly recommend it to anyone interested in taking control of their indoor environment and promoting better health through air quality awareness.

This product is perfect for growing tomatoes or any other vegetables. When you have your environment dialed in, your plants love it. And with this piece of equipment even a novice can feel like a seasoned vet. Your friends will be amazed on how well your plants are looking and that can save you time amd money in the long run. The monitor is very accurate. More dependable than those expensive models, and you really get your bang for your buck with this. I've been using this for a year straight and have had zero issues. This is very easy to set up, and worry free after you do. No hassels at all. So pick one of these up and you will be growing winning vegetables in no time. No batteries needed. Makes sure you have amazing air quality.

Don’t think this is working at all. It doesn’t go above 400ppm in my 4x4 tent with several co2 bags which I suspect don’t work either. However when I open the tent the levels shoot up over 1100ppms easily, I think this one is defective even after calibration. I’m sure my actual house co2 alarm would go off if the co2 in my home was over 1k as it’s set to do. Waste of money.

A high quality product that does exactly what it is suppose to do. Easy to use. Battery lasts a few days without recharge. The only concern is the association of colors with CO2 levels. There is a deep misunderstanding of relatively low CO2 levels as being dangerous, when in fact anything below 2500 is fine. We are in this context daily in every classroom, every lecture hall, every restaurant and even at home when eating dinner with family. Don't panic if the CO2 levels are higher than 1000. You're going to be ok.

I’ve been using the INKBIRDPLUS portable CO₂ detector for a few weeks now, and it’s quickly become one of my most useful gadgets. The readings are quick and consistent, and I love that the bright color-coded display makes it easy to see at a glance if the air quality is good, fair, or poor. The rechargeable battery lasts several days between charges, and the compact size means I can carry it in my backpack or even my pocket. I’ve used it in my home office, kitchen, car, and even at a coffee shop—eye-opening to see how quickly CO₂ levels can rise in enclosed spaces! The alarm feature is loud enough to get my attention without being obnoxious, which is great for ventilation reminders. Setup was effortless—just turn it on and it’s ready to go. The NDIR sensor technology gives me confidence in the accuracy, especially for the price. If you want an affordable, portable way to monitor CO₂ and improve indoor air quality awareness, the INKBIRDPLUS is an excellent choice.

While it worked, it was great and very helpful. Sadly though, it only worked for a little over 2 months. Given its short life, I can't recommend.

I've been using the INKBIRDPLUS CO2 Detector for a few days, and it works great! It’s lightweight, easy to carry, and the clear LCD display makes readings simple. The three indicator lights quickly show air quality, and the customizable alarm is a nice touch. Battery life is solid, lasting around 72 hours per charge. I also love the ECO mode for energy saving. Perfect for home, office, or grow tents—highly recommend!

Update 6/23/2025, The vendor reached out and provided a full refund and even went as far as to ask about the failure and using conditions. This was after the refund, I showed they care about the product enough to want to know why it failed. That says a lot about company/vedor. -*original post: Stopped charging after about a month. No longer powers up at all. It worked well until then, but one month of Usage is pretty bad
