👍【Season Special】When there is no indoor ventilation, you can accurately and quickly test the indoor carbon dioxide for your health by using our carbon dioxide measuring equipment. At the same time, our detector can monitor the indoor temperature and humidity in real time, and the clock function attached to the detector can display the accurate time. It is the best choice for your healthy life!. 👍【New Design】(1) The latest unique mold and design with 3.5-inch large TFT color capacitive touch screen; (2) NDIR SENSOR, high-performance chip to ensure higher detection accuracy. (3) One Machine Multipurpose, monitor multiple data at the same time, include CO2, temperature, humidity, time display. (4) Data Logger,Visual system logs chart for up to a week. (5) Equipped with ambient light sensor, can turn the backlight on and off automatically. 👍【Dual-Shannel NDIR Sensor】 The two-channel NDIR sensor used in the CO2 detector prevents communication of CO2 with other air and is characterized by its high accuracy, high reliability and long service life (up to 15 years). 👍【Alarm settings and data protection storage】 The alarm range can be customized, and the CO2 alarm value can be manually set. When the CO2 data exceeds the alarm value you set, CO2 detector will automatically sound to remind you. Besides, you can set a password for your carbon dioxide detector to protect your data, and then by connecting to a computer, you can view the CO2/temperature/humidity data chart of the last 7 days and export a txt file containing the data of the last 7 days. 👍【NDIR Dual-Channel Sensor VS Other Sensor】The service life of other sensors is generally only 1-3 years, while NDIR The dual-channel sensor has a service life of 15 years and is generally used in laboratory analytical instruments, durable and long service life.

Accuracy and ergonomics

One month after receiving the device: The display is easy to read even in bright daylight and from a wide viewing angle. CO2 readings are more accurate than I expected (see image). My calibrated meter reads 397ppm versus 403ppm for the monitor which is only a 2% difference. It's great for the price. Temperature and humidity levels are also good. The values in the images are off because I didn't wait long enough for them to align after moving the devices from indoors to outdoors. The only…

Pros
  • Check, measure and check
Cons
  • Ugly packaging

Not enough information

I have purchased this product and have read the information leaflet. However, there is nowhere in the magazine what a good CO2 value is! I don't know what to set the alarm for. The back of the brochure says "call our dedicated technical support" but unfortunately there is no contact information. Please help. I finally got an answer to my CO2 question, so I'm changing my rating to 5 stars. I share these numbers. Hope that helps! The relevant standard CO2 levels you participate in are as follows:

Pros
  • Industrial & Scientific
Cons
  • Available in white only

Update October 26th 2021 Another bug. It registers 607 ppm CO2 outside. The CO2 calibration function in "Settings" only offers plus or minus 100, therefore this meter cannot be recalibrated to the 413-420 range. When I asked for another refund, I found that the usual "delivery at Kohl" was not offered. So I left a message for Revain. Revain contacted me and asked what was going on with multiple returns and I explained the quality control issue with these meters. Revain then offered to stand up…
