Carbon dioxide detector three mode function
Under normal circumstances, one cubic meter of atmosphere contains about 300ppm (=7500px³) of carbon dioxide. This amount is negligible for plants. Greenhouse cultivation of plants has proved that when the carbon dioxide content in the room is high, the growth of plants is rapid and the harvest yield is also significantly improved. For this reason, carbon dioxide is often compared to an additional fertilizer for plants.
Experiments have shown that in order to make the concentration of carbon dioxide in the indoor air as good as possible to meet the needs of plants, it can be selected within the range of 400-3000ppm. Too little carbon dioxide can slow plant growth, too much can discolor or burn leaves. Because the demand of plants for carbon dioxide is determined by ventilation and light intensity, the indoor carbon dioxide concentration should be checked and adjusted frequently.
The carbon dioxide detector is a special instrument for detecting carbon dioxide, and its maximum measurement range is 2000PPM. There are three different detection modes:
(1) Manual mode: the working mode is to press once and save once, which can record the time and various environmental parameters when pressed at that time. You can also set the interval time for automatic recording, and press the stop button to stop at any time. After the data collection is completed, the data can be sent to the computer, and the software will automatically generate curve graphics, which can be printed and processed. (The host button is valid at any time, and breakpoint collection is available)
(2) Automatic mode: Set the interval time first, and the instrument can automatically record data according to the set interval time. After the data collection is completed, the data can be sent to the computer, and the software will automatically generate curve graphics, which can be printed and processed.
(3) Computer lock mode: all the keys on the host are invalid (key lock), and the samples are automatically sampled according to the interval set by the computer to ensure the authenticity and continuity of the data.
