Innovative User Interface
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.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 switched by way of an electronically controlled valving system.Data Reporting
Three unique report functions are now available with the 2i through the USB or optional thermal printer interface.
Continuous mode offers the same output as ATI’s legacy photometers to ensure backward compatibility.
Monitoring mode provides the ability to collect data at user defined intervals for long term sampling. Summary mode, which gives discrete reporting capability for individual filter
locations, can output to the thermal printer to meet customer documentation requirements.
Performance Guaranteed
To ensure consistent results in all applications and altitudes, the sampling flow rate is constantly monitored and controlled via a pulse width modulated pump.
The 2i has been independently tested and qualified to ensure compliance with all applicable electrical and safety requirements.
