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.
The 2i base instrument’s 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.
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 switched by way of an electronically controlled valving system.
Upstream aerosol mass concentrations are displayed in actual mass concentration values of micrograms per liter (μg/l). User settable Aerosol Noise Suppression (ANS) allows for more stable aerosol measurements when poor mixing is present.
