This version is ideal for users who want more than a basic CO detector.
Instead of monitoring only one gas, it gives smarter air awareness: CO₂ for ventilation and air quality, and CO for alerting against fuel-burning sources.

Why choose the 4-in-1?

• Monitors Carbon Dioxide CO₂ to help understand ventilation quality
• Detects Carbon Monoxide CO from exhaust, charcoal, grills, and generators
• Helps you know when the air feels stuffy or needs ventilation
• Displays temperature and humidity
• Alarm alert when levels rise
• Built-in flashlight
• Type-C rechargeable
• Suitable for caravans, rooms, offices, cars, and camping

When is it most useful?

• In caravans or enclosed seating areas
• In rooms or offices used for long periods
• When you want to know if the space needs ventilation
• Around generators, charcoal, grills, or vehicle exhaust
• When you want one device for both air quality monitoring and CO alert

Bottom line:
A CO detector focuses on invisible fuel-burning gas.
The 4-in-1 model gives you CO protection + air quality awareness.

Important Note:
This device is designed for monitoring and alert use only. It is not a replacement for certified safety systems or official alarm devices.
