Key Features

• Safe Power – No Built-in Battery Unlike battery-powered CO2 meters that can overheat in hot car cabins, our device plugs directly into the cigarette lighter. No battery = no safety risk, even when your car interior reaches 140°F (60°C).
• Fast 10-Second Sampling Cabin CO2 can rise quickly in just minutes. While many CO2 meters refresh every 2–5 minutes, ours samples every 10 seconds, giving you faster, real-time alerts when levels get dangerous.
• Convenient Plug-in Mounting No loose wires, no cluttered dashboard. The cigarette lighter placement provides a stable power source and a natural mounting point — just plug in and drive.
• Smart Alerts & Clear Display With an automatic beep alarm above 1400 ppm, adjustable viewing angle, and a large color screen, you’ll always know your CO2 level and car battery voltage at a glance — even in bright daylight.
• Car CO2 Monitor & Battery Voltage Display – Plug-in, No Battery Needed, Real-Time 10s Sampling, Rotatable Color Screen, Beep Alarm for High CO2, Fits 12V/24V Vehicles
• CE Certification
