FABISENSE 9C 3-in-1 CO2 Detector | NDIR Sensor | 3-Color Alarm | CO2, Temp & Humidity | for Home & Office

FABISENSE 9C — 3-in-1 CO2 Detector with NDIR Sensor & 3-Color Visual Alarm

Breathe smarter. The FABISENSE 9C uses a professional-grade NDIR (Non-Dispersive Infrared) CO2 sensor to deliver accurate, stable CO2 readings from 400 to 5000 ppm — no WiFi, no app, no subscription required. With a 3-color visual alarm system, 2400mAh rechargeable battery, and wall-mount capability, it's the no-fuss CO2 monitor for homes, offices, classrooms, and grow tents.

✅ Key Features

• NDIR CO2 Sensor (400–5000 ppm, ±50 ppm + 5%): Professional infrared sensor technology provides stable, long-term accuracy without frequent calibration. Simply press all three buttons simultaneously in an open environment to calibrate to outdoor baseline (~500 ppm) within 200 seconds.
• 3-in-1 Monitoring: Simultaneously displays CO2 concentration (ppm), temperature (°C/°F selectable), and relative humidity (%RH) on a large LCD screen — no separate thermometer or hygrometer needed.
• 3-Color Smart Visual Alarm: Instant color-coded feedback — Green (400–700 ppm, normal), Yellow (700–1500 ppm, ventilate), Red (1500–5000 ppm, dangerous). Customizable alarm threshold to suit your needs.
• 2400mAh Rechargeable Battery: Up to 24 hours of standby operation. Keep it running continuously via Type-C charger — no interruptions.
• Plug-and-Play, No WiFi Needed: Ready to use right out of the box. No internet, no app, no subscription — just charge, turn on, and start monitoring.
• Flexible Placement: Compact desktop design fits on any desk, nightstand, or bookshelf. Hanging hole on the back for wall mounting.
• Buzzer Alarm + Low Battery Alert: Audible alarm when CO2 exceeds threshold. Low battery reminder ensures monitoring never stops unexpectedly.
• Wide Application: Home, bedroom, office, classroom, car, grow tent, wine cellar, RV — anywhere CO2 monitoring matters.

⚠️ CO2 Alert Levels

• 400–700 ppm (Green): Normal — fresh, healthy air quality.
• 700–1500 ppm (Yellow): Warning — ventilation recommended. Open windows.
• 1500–5000 ppm (Red): Dangerous — immediate ventilation required. Evacuate if sustained.
