Product Description
This product is a multifunctional air quality monitor that detects Carbon dioxide (CO2), Formaldehyde (HCHO), Total Volatile Organic Compounds (TVOC), Particulate Matter <2.5 micron-sized particles (PM2.5/1.0/10), Temperature, and Humidity with clock and record function. As a scientific air quality detection device, it combines multiple air sensors with a built-in fan to allow real-time monitoring of Carbon dioxide (CO2), formalde hyde (HCHO), total volatile organic compounds (TVOC), PM2.5/1.0/10, temperature, and humidity on its digital LCD display.
Considerations
Please read the instructions carefully before using this device.
Please let the device work for short mins outdoors before use for the most
accurate results.
Please keep the manual handy for quick reference and troubleshooting.
Precautions
Avoid covering the air intake areas during use to avoid inaccurate
measurements.
Avoid the use of solvents to clean the product as residual fumes will skew air
quality readings.
Avoid water or other liquids near the product to avoid electrical damage.
Do not allow unauthorized modification or repair of this product.
Features:
- 4.3″ color liquid crystal display (LCD), 480X270 pixels
- Test variables: Carbon dioxide (CO2), PM2.5/1.0/10, formaldehyde, TVOC, temperature, humidity
- Large 3000mAh capacity Lithium battery
- On-board fan to draw in ambient air for more accurate real-time results
- 5V Micro USB charging
- Low battery warning
Instructions
Start-Up
When you long-press the center power button, the air quality monitor will boot
up. The detector will proceed through its warm-up sequence for about 3 minutes
to allow sensors to preheat and the fan to draw in fresh ambient air. This is
necessary for accurate results
- Power / OK / Menu Button used to confirm highlighted options or to tum, the device on/off by pressing for 3 seconds
- Down / Switch / Decrease Button used to scroll between interfaces
- Up/ Switch/ Increase Button, used to scroll between interfaces
- Micro USB charging port
Switching Among Data Display Formats ( Figure 1-5 )
Press the up or down buttons to switch among data display formats (figures
1-5) that display air quality readings in various formats:
Set up (Figure 6)
Double press the Power button to enter the Setup screen.
DATE: Change the date by using the up and down button. Confirm each
setting with one press on the on/off button.
TIME: Change the time by using the up and down button and by confirming
with the on/off button.
UNIT: Change the temperature unit between Celcius (C) or Fahrenheit (°F).
Buzzer: use up/down buttons to select whether to tum the alarm buzzer on
/off.
About Charging
When the low battery icon is displayed, the device needs to be charged. Insert
the included or another compatible micro USB charging cable into the device.
Attach the other end to a USB DC charger (such as a smartphone charger) that
outputs DC 5V at >=1000mA. Fully charge for at least 2-3 hours before use.
Avoid charging with a USB computer port that only outputs 500mA.
History ( Figure 3, Figure 5 )
The graph shows the last 5 data values for PM2.5, Formalde hyde and taken
every 10 minutes over the previous 50 minutes.
Alarm Threshold
Default factory value alarm threshold levels for HCHO:
0.1 mg/m3. when reaching 0.1 mg/m3, the Device alarm sounds.
HCHO (formaldehyde) ideal range: <=0.10 mg/m3 If the alarm sounds noisy, you
can tum It off.
please read page 7 about how to set the ” Buzzer “.
