The team at Air Techniques International (ATI) has recently added a new and improved photometer to its world-leading range.
The UK-based company, which is a specialist in HEPA filter and protective mask testing equipment, has launched the new 2J Aerosol Photometer, calling it a “significant advancement in filter testing”.
ATI told Cleanroom Technology that there were a couple of issues with the previous model (2i) and other photometers on the market that the 2J was attempting to address.
The 2i was launched in 2012, and ATI says it has been the number one selling photometer in the world since then. “When it was launched, it was very advanced, but for today's user, it lacks some features,” Guatam Patel, Global Products Manager at ATI, explained.
Over a decade after the launch of the 2i, ATI looked at customer needs, and determined that many had become accustomed to the user conveniences and data integrity features in portable particle counters. “The goal of the 2J was to incorporate some of those features found in particle counters,” Patel said.
What improvements does the 2J introduce?
DATA VISIBILITY: Customer feedback showed that test results are often being viewed from a ladder. In order to improve visibility of the data, the team designed a large viewing angle compared to the 2i, with all critical leak scan information on the main screen.
BATTERY: Another issue that customers were running into was working in rooms that require a leak scan test, but do not have a power outlet available. Therefore the team created an external battery for the system.
WORFLOW IMPROVEMENTS: Patel explained that the 2J allows for the saving, viewing, and printing of leak scan data. He said that this can help eliminate errors and aid in reports that the certifier generates. “These improvements may not be characterised as ‘performance' improvements, but they would be considered certifier/operator ‘efficiency’ improvements.”
No other photometer in the market offers 21 CFR Part 11 Compliance
How does the 2J compare to its competitors in 2026?
Building on these usability improvements, ATI argues that the 2J also differentiates itself from competitors in several key areas.
For one, the new photometer offers 21 CFR part 11 compliance for stored data. “No other photometer in the market offers 21 CFR Part 11 Compliance,” Patel enthuses.
The 2J allows all saved leak scan data to be viewed on the unit, sent to a thermal printer, or copied off the unit, but critically, Patel explains, it cannot be edited on the unit.
“[The 2J] offers multiple user levels, filter leak IDs for scan traceability, and an audit trail. These key features ensure 21 CFR Part 11 Compliance for the data stored on the unit.”
The other unique offering of the 2J compared with competitors is the battery. Competing systems offer an internal battery, but Patel says there is a reason the ATI team took a different approach.
The external nature of the battery allows the user to use whichever battery/power bank they want. This will allow the user to keep up with continually improving battery technology and they won’t have to worry about the battery becoming outdated. With an expected equipment life of over 10 years, this is especially important to total cost of ownership (TCO).
TCO is an increasingly important factor in running cleanroom facilities in 2026, with
