Gases Tab
The Gases tab displays real-time 1 hz data for NO
2
(ppm), NO (ppm), CO
2
(%), and CO (%). The CO
channel is a new addition, and if your model of parSYNC® does not have the CO sensor then the CO
chart will remain blank.

PM Conc and PN
The PM Conc tab displays the PM values in micrograms/cu.meter (µg/m
3
) while the PN tab displays the
particle number (PN) in number/cu.centimeter (#/cm
3
). Both, PM Conc and PN, tabs also have
coefficients established for the quadratic fit used to estimate the number and mass concentrations. Do
NOT change the coefficients unless you have a robust empirical process for determining them and
consult with the 3DATX engineering team.
The weighted contribution of each sensor to the composite particulate number and mass is displayed on
the lower right side of each attributed tab. The contributive weights of each sensor were determined by
convolution of sensor size responsivity with empirical measurements of sensor sensitivity response to
specific sample particle distribution profiles. The combination of the quadratic fit and sensor weightings
work to the provide a transfer matrix with outcome of calculated particulate concentration data.
