The monitor uses a pump to draw up air into the device and then counts the number of particles that pass through a laser in a given period of time. This number of particles corresponds to a concentration of particulate matter which can be calculated.
The device's battery lasts up to 6 hours during continuous use.
The DC1700 averages and logs the air quality data every 10 seconds. This data is saved on the device's internal memory.
The device can store about a week’s worth of continuous data, so it shouldn’t be an issue during the loan period. When the memory gets filled, the new data overwrites the oldest saved data.
The device may take +12 hours to charge if fully uncharged, keep it off while charging.
The device measures particulate matter. Small particles (0.5 microns or smaller) are displayed on the left. Larger particles (2.5 microns or larger) displayed on the right. The larger the number displayed, the poorer the air quality.
