4-in-1 Gas Detector with LCD Screen - Plug-in Carbon Monoxide & Combustible Gas Alarm, Measures Temperature & Humidity, for Home, Apartment, Hotel, Camping RV (white)

• 💨 All-Round 4-in-1 Detection System: This multi-functional detector monitors four key environmental hazards at the same time, covering combustible gas (0-15% LEL), carbon monoxide (0-999 PPM), ambient temperature (0-40°C) and humidity (0-95% RH). It delivers full-range real-time monitoring to effectively guard indoor living spaces and avoid potential safety risks.
• 🔌 Effortless Plug-and-Play Operation: Designed for user-friendly setup, it fits all standard 110V-220V power sockets with no complex wiring or professional installation required. The device undergoes a 200-second automatic warm-up process before formal operation, ready for stable use in homes, hotels, travel accommodations and RVs anytime.
• 📟 Intuitive Real-Time HD Display & Loud Alarm: Built with a high-definition backlit LCD screen that clearly presents all detection data at a glance, even in dim environments. Equipped with an 85dB high-volume alarm, it instantly emits sharp warning sounds once unsafe gas and CO concentrations are detected for timely risk prevention.
• 📋 Standardized Safety Warning Mechanism: Strictly calibrated and tested with professional safety standards. It will trigger accurate safety alerts when methane gas reaches 6% LEL or carbon monoxide hits graded thresholds of 30PPM, 60PPM, 120PPM and 300PPM, providing layered and reliable safety protection.
• 💡 Smart Energy-Saving Design: Features an intelligent auto-dimming backlight system. The screen brightness automatically lowers after 1 minute of inactivity and completely shuts off after 5 minutes, effectively reducing power consumption. It maintains stable monitoring performance while achieving long-term energy-saving operation.
