Aerosol Photometers

For Filter Testing Professionals

ACE Scientific Solutions offers a wide range of portable aerosol photometers for filter testing professionals. Air Techniques International (ATI) manufactures the most advanced, innovative, and user-friendly digital aerosol photometers available today. The 2i digital photometer is portable, rugged, and reliable and is the ideal instrument for in-situ filtration system integrity testing. The iProbe (a handheld scanner with local LCD display and controls) enables the operator to change settings without stopping to adjust the base unit, minimizing downtime.

The ATI 2i-N model includes a sealed sample train, allowing for the safe removal and replacement of contaminated sampling components. The 2i-N models are fully compatible with ASME, N511, ASME 510, ASME 509, ASME AG-1, and are fully compliant with the latest AS 1807 Australian & ISO14644-3 standards.

Innovative User Interface

The 2i base instrument’s 4.3” LCD 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 reagents 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.

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.

Space Age Probe

The iProbe with a 12ft cable 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.

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-N (the nuclear version of the 2i) is equipped with a unique, sealed sample train. The unit is engineered to allow safe removal and replacement of contaminated sampling components.

Enhanced Features

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.

Simple Maintenance

All instruments include a NIST traceable calibration certificate, as provided from ATI (Air Techniques International) at the time of purchase. Optional NATA calibration is available and this can be arranged through ACE Scientific Solutions. Annual re-calibration is also done to a NATA standard and this can be arranged through ACE Scientific Solutions. Routine preventative maintenance entails cleaning and inspection of internal sample tubing and connections, the internal reference filter, and handheld probe.
