X-Sense CO03D – CO alarm with large LCD and 10-year sensor, single unit
The CO03D pairs a Figaro electrochemical sensor with a large display that updates the CO reading every 10 seconds. It runs on three standard AA batteries, so it keeps working in a power cut.
What the CO03D brings day to day
Quality tested by TÜV Rheinland in accordance with EN 50291.
A Figaro electrochemical sensor and ST chipset detect CO accurately while minimising false alarms.
An 85 dB alarm and a quick-flashing red LED warn you as early as possible.
Three replaceable AA batteries and a 10-year sensor provide protection around the clock, even during power cuts.
Low battery and end-of-life warnings tell you when action is needed.
The large LCD shows battery life and the CO level, updated every 10 seconds, with an alarm threshold starting at 30 ppm.
