Shown below are two wireless data loggers for PM1.0, PM2.5, and PM10 measurements and they will be deployed by a construction company for construction site dust level monitoring:
The instruments are:
- 2 x HD35EDWPM particulate matter wireless data logger: for PM1.0, PM2.5 and PM10 measurement; the data are locally stored and can be transmitted to a computer on demand
- 1 x HD35APD USB dongle type base unit: for wireless communication between the computer and the wireless data loggers; 1 base unit can support multiple wireless data loggers
The model HD35EDWPM is an upgraded version of the system shown in this post. The new model integrates the sensing part and the data logging part into a single unit.
Shown below is the software screenshot:
The system can be deployed for construction site dust level monitoring. The data logger is rain-resistant and can be deployed outdoors. A clamp is included for each unit and the mechanical mounting is very easy. If the data logging interval is set to 5 min or 10 min, the internal memory can store years of measurement data.
