*The instrument can define particulate measurement peak trends up to the quantity specified.
**During sustained high dust loading periods, the instrument will report on PM data up to the quantity
specified.
Note: Sustained exposure to PM quantities above 25 mg/m³ will be logged; however, this may aect
the operating life of the particulate sensor.
