Carbon Monoxide Detector 123×70×25 mm

This compact carbon monoxide alarm brings practical protection to homes and holiday lets with a clear digital readout and a loud 85 dB alert. Its electrochemical sensor monitors CO continuously and displays real‑time concentrations on an LCD from 000 to 999 PPM, so you can spot rising levels quickly. The unit is battery powered and portable, so it works on a shelf, in a caravan or mounted on a wall.

Key points

The alarm combines audible and visual warnings, with an 85 dB sound at 3 metres and a flashing red CO LED for immediate notice. A green LED flashes every 30 seconds during normal operation and a yellow LED flags faults. The display backlight turns on automatically so you can read PPM values in low light. Ten en cuenta que batteries are not included and the device enters a 30 second countdown after installation before full operation.

Strengths

The form factor is genuinely portable, and the package includes a double sided adhesive pad plus an integrated mounting bracket and screws for wall fixing. The alarm memory leaves the red CO light flashing after an event so you know there was a prior activation. The test and silence button lets you check operation and mute nuisance alerts briefly.

Practical tips

It’s easy to carry between rooms or to take on trips, and simple installation gets it working fast. It makes sense if you want a visible PPM readout alongside conventional LED signals and an audible alarm. It might not suit you if you need mains power or rechargeable operation, as it relies on replaceable AAA batteries.
