However, the current PM2.5 and PM10 monitors are all based on the new laser technology which counts the particles and converts the count into mass per volume. This doesn’t align with the IP-10 method. Are there any newly updated requirements for testing PM2.5 and PM10? Is there a list of approved devices which can be used for the testing?
