AMT Evaluation of a lowcost optical particle counter ...

Alphasense optical particle sensor (OPCN2) The optical particle sensor (OPC) ... All lowcost PM sensors will likely require calibration factors to obtain the dry particle weight unless they actively dry the PMcontaining air stream before it enters the device. The use of heated inlets could be used to reduce the RH in the air stream but would have consequences for the power ...
