However I have a very sensitive sense of smell and I didn't want to spend a lot of my time and effort fixing what may be a very small problem. Initially I tried a CO meter however the meter itself was defective. On further investigation I determined that a CO meter was not what I needed anyway. Most modern cars do not output very much CO at all. The catalytic converter converts most CO to CO2 or water. Also, trying to detect CO means detecting a few parts per million. That's difficult. With a CO2 meter it's much easier because any decent sized exhaust leak will VERY quickly spike the CO2 levels in the car. Also, the measurements will be in the 1000s of parts per million so the error range of the meter is less important. In short, if you're looking for exhaust leaks in vehicles it will likely be easier with a CO2 meter as car exhaust is chock full of CO2. On to this meter, it works very well. I tested it in a number of situations and it detected the amount of CO2 that i would expect it to. The manual states that it samples the air once a second and as far as i can tell this is accurate. However, it is not meant to precisely measure the CO2 concentration every second. The sensor takes time to accurately reflect the ambient CO2 level. This is easy enough to test by breathing briefly on the sensor which will cause it to easily jump to over 5000ppm but it will take 30 or more seconds to return to normal. In my own car I found that the CO2 level was no different from my friend's car. So whatever I'm smelling on hard acceleration it is very likely not exhaust gases or is such a tiny amount that it's not adding to CO2 levels. That is a helpful thing for me to know. Further, this meter has applications beyond just testing the cabin of a car. It can also be used in buildings to determine if the amount of ventilation is adequate. Also, it can be used in the home to see if CO2 levels are too high (as can occur particularly when cooking or using a fireplace). I was surprised to see that in both my car and my friend's car, with the air on recirculate, we reached over 1500ppm in just a few minutes. It comes in a cute carrying case that looks like a tiny plastic briefcase. I can't imagine I'd ever use it but if you want to look like a real "pro" it can't hurt to have your meter in it's own case. Review: Value for money - Works great, as good as the more expensive ones. ## Features - HIGH PRECISION: The CO2 Detector is euipped with high accurate sensative chip, the accuracy of CO2 level is: 0-2000ppm(-50ppm/+50ppm or -5%/+5% of the reading); 2000-9999ppm(-10%/+10% of the reading); Humidity: 0.1%- 99.9%RH(Accuracy -3%/+3%RH) - Large Measurement: This CO2 Meter is designed with accurate and large measuring range, CO2: 0~9999ppm; Temperature: 14°F-140°F(-10°C/+60°C); Humidity: 0.1% - 99.9%RH; Dew Point: -20.0°C-59.9°C; Wet Bulb: -5.0°C-59.9°C - AUDIBLE AND VISUAL ALARMS - The CO2 Detector will alarm when CO2 level exceed your desired threshold, enabling you to take immediate action to improve air quality - Large LCD SCREEN: CO2 Meter has large LCD display and equipped with backlight function, it can display real-time CO2 level, temperature, and humidity readings at the same time - WIDE APPLICATION -The CO2 meter provides precise readings of carbon dioxide levels up to 9999ppm, helping you understand the air quality in your surroundings, IAQ monitoring and survey, especially on CO2 level and air ventilation become widely applied in public areas such as offices, classrooms, factories, hospitals, and hotels ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01KTJL6OK | | Alarm | Audible | | Brand | TEKCOPLUS | | Built-In Media | CO2 Meter | | Color | Yellow | | Colour | Yellow | | Customer Reviews | 4.4 out of 5 stars 291 Reviews | | Enclosure Material | ABS | | Item Dimensions D x W x H | 35.3D x 7.1W x 22.4H centimeters | | Item Weight | 132 g | | Item weight | 132 g | | Manufacturer | Tekcoplus Ltd | | Mfr Part Number | COTK-57 | | Model Number | COTK-57 | | Number of Items | 1 | | Operating Humidity | 95 percent | | Power Source | Battery Powered | | Power source | Battery Powered | | Product Style | Digital CO2 Meter | | Product dimensions | 35.3D x 7.1W x 22.4H centimeters | | Sensor Type | Non Dispersive Infrared | | Style | Digital CO2 Meter | | UPC | 713072686026 713072682325 | | Unit Count | 1.0 Count | | Upper Temperature Rating | 50 Degrees Celsius | ## Product Details - **Brand:** TEKCOPLUS - **Style:** Digital CO2 Meter - **Power source:** Battery Powered - **Colour:** Yellow - **Item weight:** 132 g ## Images ![Tekcoplus Co2 Meter Portable Detector Digital Monitor With Alarm Function Carbon Dioxide Temperature And Humidity Meter, Ndir Sensor Indoor Air Quality For Home Office Grow Room - Image 1](https://m.media-amazon.com/images/I/61ug6rENQIL.jpg) ![Tekcoplus Co2 Meter Portable Detector Digital Monitor With Alarm Function Carbon Dioxide Temperature And Humidity Meter, Ndir Sensor Indoor Air Quality For Home Office Grow Room - Image 2](https://m.media-amazon.com/images/I/71dSK-tPeQL.jpg) ![Tekcoplus Co2 Meter Portable Detector Digital Monitor With Alarm Function Carbon Dioxide Temperature And Humidity Meter, Ndir Sensor Indoor Air Quality For Home Office Grow Room - Image 3](https://m.media-amazon.com/images/I/713EyY2FKRL.jpg) ![Tekcoplus Co2 Meter Portable Detector Digital Monitor With Alarm Function Carbon Dioxide Temperature And Humidity Meter, Ndir Sensor Indoor Air Quality For Home Office Grow Room - Image 4](https://m.media-amazon.com/images/I/81d9xdZgjwL.jpg) ![Tekcoplus Co2 Meter Portable Detector Digital Monitor With Alarm Function Carbon Dioxide Temperature And Humidity Meter, Ndir Sensor Indoor Air Quality For Home Office Grow Room - Image 5](https://m.media-amazon.com/images/I/71JqHPQA6pL.jpg) ## Questions & Answers **Q: What does this CO2 meter measure?** A: It measures carbon dioxide (CO2), temperature, humidity, dew point, and wet bulb temperature in real time. **Q: What type of sensor does the device use for CO2 detection?** A: It uses a stable NDIR (Non-Dispersive Infrared) sensor for accurate and reliable CO2 measurement. **Q: What is the CO2 measurement range and accuracy?** A: The CO2 range is 0–9999 ppm.
