​Types of CO Alarms

There are three basic types of CO sensors discussed below: metal oxide, biomimetic and electrochemical
Note that although there are performance differences between the technologies, all detectors are tested and approved for their operation.​ ​​

Metal Oxide​

How It Works:
​The original technology for detecting CO. Heated tin oxide reacts with CO to determine the levels of the toxic gas. Must connect to house power.
Features:​ 
​No need to remember to check the batteries as the unit plugs in. Battery backup is available for up to 20 hours. ​

Biomimetic​

How It Works: 
Gel coated discs darken in the presence of CO. Color change sounds an alarm.
Features: 
​Les​s expensive technology. Can be battery operate​d.

Electrochemical​

How It Works:
Ch​emical reaction with CO creates an electrical current, setting off an alarm.
Features: 
Highl​y sensitive and accurate readings at all CO levels. Most units come with a continuous digital readout and a memory feature that allows you to check past CO levels. Fast reset time.
