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:

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.

A system was integrated by OTM for construction site particulate matter (PM1.0, PM2.5 & PM10) measurement, with the following components:

  • Delta Ohm PMsense-M particulate matter transmitter with MODBUS-RTU output
  • Delta Ohm HD35EDW-MB wireless data logger supporting MODBUS-RTU output

Listed below are the key specifications:

  • PM measuring principle: laser scattering
  • Calibration certificate can be provided on additional cost
  • Measuring range: 0 – 1000 μg/m3 for each component
  • IP67 protection for both transmitter and data logger, suitable for outdoor installation
  • Wireless connection between data logger and base unit
