The digital display shows carbon monoxide readings that are taken every 15 seconds, indicating any changes in CO levels. The alarm can be wall mounted or free standing.

Review: Reliable and Ideal for Boats/Caravans etc - This is the 3rd of these units I've purchased, one for the house and two for boats. They are ideal for the latter as they meet the spec for damper/colder environments. The peak display gives assurance you haven't got anywhere near a dangerous CO level. Highly recommended if you have a solid fuel stove or gas hob/oven.
Review: Impressive features - I liked the LCD display which gives accurate readings of faults rather than just a beep!

### ⭐⭐⭐⭐⭐ We haavn't been gassed yet!
*by A***R on 5 May 2025*

Great detectors. We bought one for each floor of our house. It's discreet, with a flash once a minute to tell you that it's still operating, while lot attracting too much attention. It's easily fitted and has a good slide on bracket that fits to the wall so the detector can be removed for examination and easily slid back into position.
