The UEi ACA/R Advanced Combustion & Refrigeration Analyzer with Nitric Oxide Sensor combines commercial combustion analysis and refrigeration diagnostics in a single all-season platform. This configuration includes a nitric oxide (NO) sensor for expanded combustion testing. 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 nitric oxide (NO) measurement, 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.
