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.

Hazardous Environments
Designed for the rigors of nuclear and other hazardous applications, the 2i can be equipped with a unique, sealed sample train. The unit is engineered to allow safe removal and replacement of contaminated sampling components.

Simple maintenance
Annual NIST traceable calibration service is provided by ATI or an ATI-certified calibration facility. Calibration includes setting the aerosol reagent references, sample flow reference points, operating voltages, and servicing the light scattering chamber assembly. Routine preventative maintenance entails cleaning and inspection of internal sample tubing and connections, the internal reference filter, and iProbe.
