Newentor CO2 Monitor, Air Quality Monitor Indoor Carbon Dioxide Detector with Voice Alert Large Display, Temperature Humidity, Alarm Clocks for Home, RV, Office, Classroom, 400-5000ppm, Black

Sensitive, informative and precise. The only thing: a dimmed mode, the two modes available are too bright to be used at night.

This meter seems to be very good so far. Not so sure about using it with batteries as it's sample rate is too slow but plugged in on a desktop it samples every 6 seconds. So far it seems to be performing well enough and reacts very quickly to any increase or decrease in C02 levels. The alarm threshold for ppm is adjustable which is good as it can be custom set for my circumstances. Clear display with various other readings such as temp, humidity time, date etc.

Where do I start, this is the perfect little box if you need a CO2 monitor, it does that and a whole bunch more. It will tell you the temperature, the humidity, it has a clock and date, it’s just perfect to glance at and get all the information you need in one place. The screen is bright and it all feels really well made. This was a very good purchase and a really good company to buy from.

Simple to use, simple to understand, huge impact on air quality. I went for this as any "smart" or app backed ones are far more expensive and it's made a huge difference in my home office and the quality of the air in there as the day goes on.Recommended to colleagues as well and at least 5 others have been bought by them. If you're curious about CO2 levels in your spaces, I highly recommend trying this.

Not to be confused with a carbon monoxide detector this device is a must for people who are aware of the detrimental effect high CO2 levels can have on your health. It's a cool looking piece of kit and is incredibly sensitive to changes in CO2 levels. If you read the instructions carefully it is easy to set up and use. You will need a 5V usb power supply for real time data. I was surprised how quickly carbon dioxide levels increase and I have now started to open windows to provide ventilation which quickly reduces the level.

The media could not be loaded. It does what it says.Pros:Big Screen - Big Numbers - Accurate - Instant Update for PPM - Humidity (to the right) Temperature: Fahrenheit and Celsius - Time: 24hr & 12hr - Two Alarms - Date & Day (Sat, Sun, Mon formate bottom right) - Easy Menu.Cons:(1) Too bright for me to keep in the bedroom. (2)Only works on three AAA batteries (not included)(3) Charging cable is not a USB one.(4) PricyHope this helps you.

A clever device which works well but the setting up takes time and is irratating to me. Younger folk will take easier to this. If the power is lost it means doing it over again. If careful it may be avoided by always having batteries and USB power and only changing the batteries when the power is present. I now know I only need CO2, temp and humidity so will buy a simpler device.

Setting up instructions are clear and easy to follow.
