About this item
  • 【Ultimate 4-in-1 Safety Guardian】 Monitor combustible gas (0-15% LEL), Carbon Monoxide (0-999 PPM), temperature (32-212℉), and humidity (0-95% RH) all in one compact device. This comprehensive detection system eliminates the need for multiple sensors, providing a all-around safety net for your family against invisible threats.
  • 【Plug-and-Play & Universal Compatibility】 No complex wiring or professional installation required. Designed for ultimate portability, it fits any 110V-220V AC outlet. Whether you’re at home, in a hotel, traveling, or living in an RV, simply plug it in, wait for the 200s auto-preheat, and enjoy immediate peace of mind.
  • 【Real-Time LCD Display & 85dB Urgent Alarm】 The crystal-clear backlit LCD provides live data at a glance, even in the dark. In the event of a leak, the piercing 85dB audible alarm ensures you and your loved ones are alerted instantly, providing crucial seconds to react and evacuate safely.
  • 【Precision Sensing & Rapid Response Standards】 Built with high-sensitivity sensors to meet rigorous safety standards. It triggers alerts when gas levels exceed 6% LEL or CO reaches critical thresholds (30/60/120/300 PPM). Our intelligent response system adapts from gradual monitoring to immediate warnings, ensuring no danger goes unnoticed.
  • 【Smart Energy-Saving & Sleek Design】 Engineered for efficiency with an Auto-Dimming Backlight that reduces brightness after 1 minute and turns off after 5 minutes to prevent light pollution and save power.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
