UEi ACA/R Advanced Combustion and Refrigerant Analyzer
Don’t miss out on the great benefits of UEi Service+.
Register your analyzer with UEi and get notified when its time to recertify.
The UEi ACA/R Advanced Combustion & Refrigeration Analyzer combines commercial combustion analysis and refrigeration diagnostics in a single all-season platform. Designed for HVAC professionals who service both heating and cooling systems, the ACA/R delivers combustion testing, refrigeration diagnostics, pressure measurements, temperature measurements, and indoor air quality data through an intuitive, high-contrast graphical display. Optional wireless refrigeration probes allow users to view superheat, subcooling, vacuum, and pressure measurements directly on the analyzer or through the free UEi HUB app.
Featuring a hydrogen-compensated CO sensor, CO2 measurement, O2 sensing, differential pressure measurement, draft testing, heat exchanger testing, and room CO monitoring, the ACA/R is equipped to handle demanding commercial and residential applications. Wireless connectivity, optional theft protection through UEi LOCK, low-flow protection, calibration reminders, and optional thermal printing help streamline testing, reporting, and equipment management. The analyzer is backed by UEi Service+, offering same-day recertification, annual warranty extension eligibility, and free shipping with qualifying recertification programs.
