Editor's Notes & Price Research
The digital readout of the Kidde Plug-In Digital Carbon Monoxide Alarm with 9-Volt Backup continuously displays carbon monoxide levels from 30 to 999 parts per million (PPM) and will sound an 85 dB alarm when dangerous levels are reached. Protection continues during power outages thanks to a 9-volt battery backup. -TheAnarchist
