The Audio Output feature on the P-T
RAK
®
particle counter provides
an audible feedback which is proportional to the measured particle
concentration. When this feature is turned On, you will hear an
audio signal which will give you an indication of changing particle
concentrations. This feature may be particularly useful when you
are attempting to detect highly localized sources of particulate, in a
low light condition. A sample screen is shown below.
