2i Digital Aerosol
Photometer
The most advanced, innovative and user friendly digital aerosol photometer
available today, the ATI 2i is portable, yet rugged, and the ideal instrument for in-
situ filtration system integrity testing. Utilizing the iProbe provides full functionality
away from the base unit, minimizing downtime and maximizing efforts in the field.
The 2i is also available with a sealed sample train for use in nuclear and other
hazardous environments.

Innovative User Interface
The 2i base instruments 4.3 Liquid Crystal Display gives life to the easy to use, menu driven
interface. Aerosol measurements and pump sampling rates are prominently displayed for easy
viewing. System parameters and selections such as alarm types, alarm set points and aerosol
reagent are shown on the lower menu bar, while icons at the top of the screen give the status of
connected peripherals, reporting functions, and aerosol noise suppression selections.
iProbe
The iProbe acts as an extension of the base instrument through
a nearly identical user interface. All status and selection icons
from the base unit are represented on the iProbe. With the press
of a button, the sampling location can be remotely selected and
