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

The device shows the current CO concentration on a display and only emits an audible and visual alarm when a critical value is reached. There is therefore a constant measured value display that triggers an alarm when defined limit values are exceeded. The alarm times vary depending on the CO concentration (e.g. 3 minutes at 300 ppm).
