音响便携式PM2.5检测仪

  

 

 

操作指南：

 

1. 把USB连接线一端插入空气侦探右侧的插孔，另一端接通电源。（充电宝，电脑USB, 5V USB适配器均可作为电源）。

2. 通电之后，空气侦探即显示空气质量浓度值，大概20秒左右浓度值会达到稳定状态。

3. 短按空气侦探上方触摸按键并保持0.2秒以上的按键操作，空气侦探将轮流显示温度，湿度和PM2.5浓度三个读数中的一个。

4. 如需关掉空气侦探，需拔掉USB电源线。

Operational Guidelines:

 

1. Insert one end of the USB connecting line into the jack on the right side of the air detective, and the other end is connected to the power supply. Charging treasure, computer USB, 5V USB adapter and son on can all be used as power supply.

2. After powered up, the air detective shows the air mass concentration value, which will reach a stable state in about 20 seconds.

3. Press the touch button  on  he top of the air detective and hold it for more than 0.2 seconds. The air detective will display one of the three readings of temperature, humidity and PM2.5 concentration in turn.

4. If you need to turn off the air detective, you need to unplug the USB power cable.
