DS-100PRO Portable CO & CO2 Detector for Travel, 4-in-1 Magnetic Carbon Monoxide and Carbon Dioxide Detector, Audible & Visual Alarm, 3-Day Standby, CO & CO2 Monitor for Home, Tent, RV

GasDoc DS-100PRO Dual Gas Detection – CO₂ + CO: The DS-100PRO is a portable detector that combines carbon dioxide (CO₂) and carbon monoxide (CO) monitoring in one device. It provides accurate measurements of CO₂ levels (400–5000 ppm) and CO levels (0–500 ppm), helping you safeguard indoor air quality and prevent harmful gas exposure. Real-Time Display & Multi-Function: The DS-100PRO shows real-time CO₂, CO, temperature, and humidity values. The intuitive interface ensures you can quickly read air quality conditions for daily use at home, in offices, classrooms, or during outdoor activities. Audio-Visual Alarm & Adjustable Thresholds: For CO₂: Green: 400–799 ppm (Safe) Yellow: 800–1499 ppm (Caution level) Red: ≥1500 ppm (Warning level) For CO: Green: 0–49 ppm (Low level) Yellow: 50–99 ppm (Warning level) Red: ≥100 ppm (Dangerous level) Both CO and CO₂ alarm thresholds can be customized according to your needs. The default CO alarm is set at 50 ppm. Safe Testing Method: To test the CO function safely, you may use smoke from a lit cigarette or smoldering paper in a sealed non-flammable container. For CO₂, exhaled breath can be used as a simple test.

• All-in-One CO & CO2 Detector: DS-100PRO detects carbon monoxide (0–1000 ppm), carbon dioxide (400–5000 ppm), temperature, and humidity. It triggers alarms at 50 ppm CO or 1500 ppm CO2, ensuring early warnings and all-round air quality protection
• Portable & Travel-Ready: Lightweight and pocket-sized with a lanyard and built-in magnet. Clip it to your backpack, hang it in your tent, or attach securely to metal surfaces. Once powered, it runs continuously for up to 72 hours. Ideal for home, car, office, tent, or travel
• Dual Audio-Visual Alarms: Features a three-color indicator (green/yellow/red) and a loud buzzer. Supports customizable alarm thresholds, allowing personalized safety parameters for different scenarios such as home, garage, tent, and more
• Dual-Gas Protection: Carbon monoxide (CO) detection helps prevent poisoning from faulty heating systems, fireplaces, or vehicle exhaust, while carbon dioxide (CO2) monitoring indicates ventilation quality in enclosed areas such as homes, indoor growing spaces, or wine cellars — offering full protection against multiple hazards
• How to Properly Test CO: Easily verify detector responsiveness by placing a small smoke source, such as burning paper or a cigarette, near the sensor — keeping a safe distance from smoke or ash. The alarm should activate within seconds. Not recommended to test with car exhaust or gas stoves, as normal operation usually does not release detectable CO
