Desktop Indoor Air Quality Monitor with Temperature, Humidity, and CO2 Detection

The CO2 Monitor is a desktop unit designed for fast and accurate measurement of CO2 levels, air temperature, and humidity. It features a triple LCD display with real-time clock and calendar, along with programmable alarms for enhanced indoor air quality (IAQ) monitoring. The unit is equipped with a 15° tilt angle for easy reading and includes both Automatic Baseline Calibration (ABC) and Manual Calibration options.

Features & Benefits

• Triple LCD Display: Simultaneously shows CO2 level, temperature, and humidity for comprehensive air quality monitoring.
• Real-Time Clock & Calendar: Allows easy tracking of air quality changes over time.
• 15° Tilt Angle: Provides an easy-to-read display for quick monitoring.
• Indoor Air Quality Indicator: Displays air quality levels as “Good,” “Normal,” or “Poor” based on CO2 concentration.
• NDIR Sensor: Maintenance-free Non-Dispersive Infrared (NDIR) sensor ensures stable and accurate CO2 detection.
• Audible & Visual Alarms: Alerts when CO2 levels exceed set limits and automatically stops when levels return to normal.
• Automatic Baseline Calibration (ABC): Automatically adjusts baseline readings for long-term accuracy.
• Manual Calibration: Allows manual adjustment of CO2 calibration with a calibration indicator.
• Max/Min Value Recall: Easily review maximum and minimum recorded CO2 levels for detailed analysis.
• Selectable Units: Choose between Celsius and Fahrenheit for temperature readings.
• CE Marking: Certified to meet European safety and health standards.
