1. Product Overview
The IGERESS Indoor Air Quality Monitor is a portable device designed to measure and display key indoor air quality parameters. It provides real-time readings to help you assess your living environment.
The monitor is equipped with multiple sensors to detect the following:
- Formaldehyde (HCHO)
- Total Volatile Organic Compounds (TVOC)
- Particulate Matter (PM1.0, PM2.5, PM10)
- Air Temperature
- Relative Humidity
The device features a 7-inch LCD screen for clear data visualization, an audible alarm, and a color-coded interface to indicate risk levels.
5. Operating Instructions
Understanding the Display
The main screen displays all measured values simultaneously. Each parameter is shown with its numerical value and unit (e.g., mg/m³, μg/m³, °C, %RH).
The background color of the display or specific indicators will change to reflect the overall air quality level:
- Green: Good - All parameters within safe ranges.
- Yellow: Moderate - One or more parameters are elevated.
- Red: Poor - One or more parameters exceed safe thresholds, triggering the audible alarm.
Using the Function Keys
The four buttons allow you to:
- Switch between different display views or data pages.
- Enter the settings menu to adjust parameters like alarm thresholds or unit preferences (if configurable).
- Scroll through options within menus.
- Confirm selections.
- Mute or acknowledge an active alarm.
Refer to the on-screen prompts for specific key functions.
Alarm System
When the concentration of HCHO, TVOC, or PM exceeds the preset safety limit:
- The device will emit a continuous or intermittent beep.
- The screen color will change to red (or a warning color).
- The numerical value for the exceeding parameter will typically flash or be highlighted.
To silence the audible alarm temporarily, press any button. The visual warning will remain until levels return to a safe range.
Initial Setup and Calibration
- Charge the Device: Connect the provided USB cable to the monitor and a standard USB power adapter (5V/1A) or computer port to fully charge the internal battery before first use.
- Power On: Press and hold the power button to turn on the device.
- Initial Calibration: For accurate readings, the device should be calibrated before its first use and periodically thereafter. Follow the on-screen prompts or refer to the manual for the calibration procedure. This typically involves placing the device in a clean, well-ventilated area for a period to establish a baseline.
Taking Measurements
- Place the monitor in the area you wish to test (e.g., bedroom, living room, office, car). Ensure it is on a stable, flat surface.
- Allow the device to run for at least 5 minutes to stabilize and provide accurate readings. Air circulation around the device is necessary.
- Use the 10-key interface to navigate the menu. You can view:
- Overall Interface: Displays all key parameters (HCHO, TVOC, PM2.5, Temp, Hum) simultaneously.
- Individual Parameter Screens: Navigate to view detailed readings and historical data charts for specific metrics like HCHO or PM2.5 over time.
- Settings Menu: Access options for alarm thresholds, unit settings, data logging intervals, and device calibration.
- The color screen will show numerical values. Pay attention to any on-screen warnings or audible alarms indicating high pollution levels.
Data Logging and Chart View
The device can record air quality data over a user-defined period. To use this feature:
- Access the data logging mode from the main menu.
- Set the desired logging interval (e.g., every minute, every 10 minutes).
- Start the logging session. The device will store the data internally.
- After the session, you can navigate to the chart view to see graphical trends of HCHO, TVOC, Temperature, or PM2.5 levels over the recorded time.
