Product Description
Siemens QSA2700 Dust Particle Monitor, a fine dust particle sensor is designed to measure and relay PM2.5 and PM10 indoor concentrations. This Dust Measuring Device has a built-in proximity sensor and enters energy-efficient mode if no interference has been observed (around 1 m) in the last few minutes in front of the sensor. In energy-efficient mode, the display is off and the sensor operates and constantly transmits signals. This 3-family QSA set of QSA2700 is display-free, and QSA2700D has an LCD panel, AQS2700 serves as the replacement sensor module, and MODBUS Communication Selection, too.
Features of Siemens QSA2700 Dust Particle Monitor:
- This Dust Particle Monitor is designed to measure and transmit indoor concentrations of PM2.5 and PM10.
- 0…10 V and Modbus output
