Dienmern PM2.5 Air Detector PM 10 Air Quality Monitor Gas Analyzer PM 1.0 Detector with TVOC AQI HCHO in Outdoor indoors

Features:

1. HCHO (formaldehyde) detection

2. TVOC detection

3. PM2.5 dust detection

4. Temperature detection;

5. Humidity detection:

6. Built-in large capacity lithium battery

7. Time display

Instructions:

(1)  Time setting: Press the setting button, the hour digit flashes, press UP or DWON to set the corresponding hour data, then press the setting button, shift to the minute, press UP or Down to set the minute.

(2) Shutdown: Press and hold the power button for 3 seconds

(3) Preheating: Every time after startup , there will be a 200 second automatic countdown on the screen. This is the preheating process of formaldehyde sensor detection.

(4) Calibration: After turning on the machine, put the detector in a ventilated place for more than 10 minutes and thenlong press the setting button for 3 seconds, the instrument will sound a tone,The HCHO TVOC data on the LED screen will return. 0.000, then calibration is successful.

(5) Detection: After the calibration is completed, put the detector in the indoor rooms to be tested.the current value is the detected value. If the standard is not exceeded, the instrument will not emit a tone.

The standard values are: HCHO (formaldehyde): standard <=0.10mg/m3

TVOC: <=standard 0.6mg/m3

(6) Battery display: If the battery is fully charged, the battery symbol will be displayed in white. If the battery symbol is displayed in red, it is already understand low power statu.

(7) Power supply: If the battery no power, use the USB power supply (output voltage is DC5V/1A) to supply power to the DM605 through the USB cable, and it will also charge automatically. When charging, the battery symbol is red to indicate that it is charging, and when the green light is on, it is full.

Precautions:

1. Any sensor will be interfered by certain external substances during work. Therefore, when using this product for testing, please avoid contact with other chemical volatile gases such as alcohol and perfume, and smoke. "

2. The indoor air is always flowing, and the sensor is connected at different time points. The air in the air hole may be different, and the content of formaldehyde in the air may be different. Therefore, it is normal for the detection value to float up and down a small amount.

3. When using, avoid the accuracy of the air blower, blower and other strong winds directly blowing into the venting hole. The product should be placed in a relatively stable area with air flow to make the detection more accurate.

4. Before detecting formaldehyde and TVOC in the bedroom, living room, cloakroom, etc., seal the window door for 24 hours and then test it. The effect is better. Check multiple points in one room. The average reading of multiple points is The average amount of air in the room.
