· PM sensor boxes were constructed using four lowcost PM microsensor models. Three boxes were deployed at each of two schools in Southampton, UK, for around one year and sensor performance was ...
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 ...
The Alphasense PID sensor is offered in two models, A12 and AH2. They are virtually insensitive to humidity changes, providing unparalleled performance in a variety of applications. PIDA12 has a linear dynamic range of 50 ppb to 6,000 ppm (Isobutylene). PIDAH2 has a linear dynamic range of 1 ppb to 50 ppm (Isobutylene).

The Alphasense OPCN2 / OPCN3 sensors are an optical particle monitor that measures PM , PM and PM 10. Alphasense is certified with ISO 9001:2015. Principle of Operation The Alphasense OPCN2 / OPCN3 sensors use laser beams to detect particles from micron to 17 micron in diameter with 16 bins ( to 40 µm with 24 bins for OPCN3). Count measurements are converted …
· ABSTRACT Due to their affordability, compact size, and moderate accuracy, lowcost sensors have been studied extensively in recent years. Different manufacturers employ different calibration methodologies and provide users with calibration factors for their models. This study assessed the performance of nine lowcost PM monitors (AirVisual, Alphasense, APT, Awair, Dylos, Foobot, …
With over 25 years experience in the design and manufacture of Gas and Particulate sensors, Alphasense has established a reputation as a reliable source for a wide range of gas sensor technologies. The Company supplies high quality Oxygen,CO 2, toxic and flammable Gas sensors to many of the world’s leading industrial OEMs.
· Alphasense sensors can be used for both static and dynamic PM monitoring, and their further specification is as shown in Table 1. The recorded data can be directly transferred from Alphasense to Computer through the USB port. Alphasense sensor is among the lowcost dust sensors which are listed USEPA.
