2i Portable Photometer
Printable Specification SheetDescriptionThe 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 InterfaceThe 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.iProbeThe 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 ReportingThree 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 GuaranteedTo 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 EnvironmentsDesigned 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 maintenanceAnnual 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.
Enhanced FeaturesUpstream 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.
