Introducing the Newest 2 in 1 LED Digital Gas Smoke Alarm — a compact, battery-powered safety device that monitors both carbon monoxide and smoke with a clear LCD readout, audible alert, and precise LED indicators. Designed for homes, classrooms, offices, and more, this dual-sensor detector provides immediate, actionable warnings so you can respond quickly and safely.

• Dual-sensor technology: electrochemical carbon monoxide sensor paired with an infrared photoelectric smoke sensor for fast, reliable detection.
• Bright LCD display keeps you informed with real-time readings and device status at a glance.
• Powering option: 3 AA 1.5V batteries, delivering low current consumption for long standby life and efficient operation.
• Smart alerts: battery low prompt, alarm memory function, and a silent mode to pause alarms when needed.
• Double warning system: simultaneous sound and LED indications ensure warnings are noticed even in noisy environments.
• Robust build: SMT industrial manufacturing delivers strong stability and durable performance.
• Audible alert: sound output greater than 80 dB to ensure warnings cut through ambient noise.
• Compact design: 104 mm diameter and 35 mm height with a clean white plastic finish.
• Low power consumption: quiescent current under 80 µA; alarm current under 30 mA for efficiency and reliability.
• Coverage area: up to 80 m² for spaces with ceiling heights between 6 and 12 meters; up to 60 m² for spaces with ceilings 6 meters or lower.
• Operating conditions: works from 0 to 50 °C and 10% to 95% relative humidity for versatile placement.
• Detection ranges: CO 0–999 ppm; smoke sensitivity 0.1% to 9.9% (density measurement).
