4.6.7. RANGE UNITS
The T100 can display concentrations in parts per billion (10
9
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
3
, MGM). Changing units affects all of the display,
analog outputs, COM port and DAS values for all reporting ranges regardless of the
analyzer’s range mode.
