Does the device display a constantly verifiable measured value, or only from a critical value?

The device displays a measured value on the integrated LCD display from a CO concentration of 10 ppm and checks the air every 4 seconds. An acoustic alarm and a red flashing LED are only triggered from a critical value of 43 ppm, whereby a pre-alarm function is also activated from this value. This means that the measured value can be constantly checked and is visible, not just from a critical value.
