mols per mol, PPB), parts per million (10
6
mols
per mol, PPM), micrograms per cubic meter (µg/m
3
, UGM) or milligrams per cubic meter (mg/m

, MGM).
Changing units affects all of the display, analog outputs, COM port and iDAS values for all reporting ranges
regardless of the analyzer’s range mode.
