- LARGE LCD DISPLAY & HIGH SENSITIVITY: Clearly displays the battery life and the real-time CO levels taken from the surrounding air, with an updated measurement taken every 10 seconds; responds to various CO threshold levels, with the lowest alarm threshold at 30 PPM, ensuring your ultimate CO protection
