CO/CO2 and Air Quality Meter | Sensor | Portable | 0-1000ppm/400-5000ppm | 4 in 1

Technical Specifications
Power supply: Rechargeable 1000 mAh lithium-polymer battery
Charging port: USB Type-C (compatible with QC2.0, PD3.0, 10–65 W chargers)
Standby time: up to 120 h in power-saving mode
Measurement ranges:
• CO: 0–1000 ppm (±10 %)
• CO₂: 400–5000 ppm (±50 ppm + 5 %)
• Temperature: -10°C ~ +50°C (±1.5°C) / 14°F ~ 122°F (±2.7°F)
• Humidity: 0–95 % RH (±5 % RH)
Display: Backlit LCD showing CO, CO₂, temperature, humidity, battery status

Alert system:
CO:
• Green (0–49 ppm) – safe, no sound
• Yellow (50–99 ppm) – warning, cyclic beep
• Red (100–1000 ppm) – danger, cyclic beep

CO₂:
• Green (400–699 ppm) – safe, no sound
• Yellow (700–1499 ppm) – warning, no sound
• Red (1500–5000 ppm) – danger, cyclic beep

Housing: Magnetic end for convenient attachment to metal surfaces
Warranty: 1 year

Functions
• Simultaneously measures 4 parameters: CO, CO₂, temperature, humidity
• High-precision sensors for fast response and accurate results
• Three-color visual indicator for clear risk level determination
• Audible alarm at dangerous concentration
• Magnetic mount for easy installation without extra brackets
• USB-C fast charging with wide compatibility
• Portable design for both indoor and outdoor use

Applications
• Construction and renovation sites – ensuring worker safety
• Home environments – monitoring air quality and assessing ventilation needs
• Industrial buildings – controlling CO/CO₂ concentration
• Cars and garages – protection from dangerous gas accumulation

Pros
• One device – 4 measurement functions
• Clear and easy-to-understand indication – colors and sound
• Long operating time without charging (up to 120 h)
• Fast charging via USB-C
• Compact and mobile – can be used anywhere
• Magnetic mount – no extra brackets needed

Cons
• No permanent power connection for long-term stationary operation
• CO₂ warning signal is triggered only in the danger zone (>1500 ppm), not at the warning level
• Not suitable as the sole safety device in enclosed spaces with possible rapid gas accumulation
