Description of each gas concentration level
The gas concentration is classified into 4 levels and
displayed numerically (the specific numerical classification is
shown in the table below), and the color of the icon
corresponding to a single gas changes according to the gas
concentration. When any one of the following alarm values
is reached, the device will emit a ticking alarm sound and
the indicator light will flash continuously.
