Fungsi
Alat yang digunakan untuk mengukur konsentrasi partikel debu di udara. Dust monitor dapat digunakan untuk memantau kualitas udara di lingkungan industri, perkotaan, atau alam. Dust monitor dapat membantu mengidentifikasi sumber polusi udara, mengevaluasi dampak kesehatan, dan mengambil tindakan pencegahan atau pengendalian.
Cara Kerja
- Power key [ ]: press to power on/o
- Start sampling [RUN]: 1. At the main interface: press [RUN] to start data sampling. 2. Each sampling lasts for 120s. During sampling, the data will be updated every 20-30 seconds, and other keys are disabled and cannot operate, only power key can function.
- Enter key [ENTER] 1. At the historical record mode: press [ENTER] to conrm the page number of the selected pages. 2. At the functional parameters mode: 1. Press [ENTER] to enter function change. 2. Press [ENTER] to save the changes.
- SHIFT key [SHIFT] 1. At the historical record mode: press [SHIFT] to select the unit’s pages. 2. At the functional parameters mode: press [SHIFT] to select the functional parameter items to be changed.
- Page up key [▲] 1. At historical record mode: used to increase by 1/page up by one page. 2. At functional parameters mode/change state: used to increase by 1; switching unit and select “yes” or “No”
- Page down key[▼] 1. At the main interface: press to enter the historical record→ the functional parameter. 2. At the historical record mode: used to decrease by 1/page down by one page. 3. At the functional parameters mode/change state: used to decrease by1; switching unit and select “yes” or “No”
- Back key [BACK] 1. At historical record and functional parameters mode: back to the main interface. 2. When changing a parameter: press to exit from changing.
MEASUREMENT
The instrument should be placed in an open space before measurement to avoid blocking of the sensors.
- Press the power key to switch on.
- Press [RUN] key at the main interface to enter the sampling state of 120s. The data will be updated every 20-30 seconds during the 120s sampling time.
- Do not operate the instrument while sampling.
- After sampling, the result will be displayed on the screen. 5. Users may enter “functional parameter" interface to set the particle unit so as to recognize the switching of measurement mode (counting mode/weighing mode).
