As you know, the cause of many problems with well-being and chronic fatigue syndrome may be an excess of carbon dioxide (CO2) in the room air ( megamozg.ru/post/4982 ). In almost all urban apartments, ventilation is not sufficient to maintain a comfortable CO2 level. It is very important to have a CO2 level meter at home in order to open the window at least on time.
The MASTER KIT MT 8057 carbon dioxide detector is now actually the cheapest on the market. In the online store MedGadgets from 4950 rubles .
The device displays the CO2 level and temperature; it can be connected to a computer to plot CO2 changes over time.
The screen alternates between CO2 level (15 seconds) and temperature (5 seconds).
Three LEDs (green, yellow, red) indicate the level of comfort in terms of carbon dioxide concentration. By default, green is up to 800 ppm, yellow is 800-1200 ppm, red is more than 1200 ppm. If desired, these ranges can be changed.
There are two buttons on the back with which you can select the display ranges, calibration modes, altitude and temperature scale.
Included is a device, a USB-MicroUSB cable and instructions.
No power supply included. You can use any charger with a USB output. On average, the device consumes 22mA, but at the peak during measurement, consumption increases sharply.
The same device is sold under the name RAD-0301. On co2meter.comYou can download a datalogging program for it.
When connected to a computer, the device is recognized as a standard input device. The program does not require installation and configuration. It shows changes in CO2 level and temperature over the last hour or over a long period.
You can clearly see how in three hours the level of CO2 with a closed window and when one person is in the room increases from 600 to 1000 ppm, and then after opening the balcony door it drops to 600 ppm in ten minutes.
I compared the instrument readings with the AZ Instruments 7798 CO2 datalogger . MASTER KIT turned out to be very accurate - the readings diverged no more than by 50 ppm - this is an excellent result.
